It says much about modern times that on hearing a commotion next door, Tom Penn – acting ‘purely out of instinct’ – reached for his smartphone and pressed record.
The phone call to police would come later. First, Mr Penn, 30, wanted evidence that might prove ‘important’.
Such a reaction had nothing to do, of course, with the fact that those engaged in the crockery-breaking barney just after midnight on Friday were none other than Boris Johnson and his 31-year-old girlfriend Carrie Symonds – or that the sleuthing Mr Penn and his wife Eve Leigh are avowed Remain supporters.
Under fire: Tom Penn and Eve Leigh, who live in the same block as Carrie Symonds in Camberwell, south London, said he heard screaming, banging and then silence in the early hours of Friday morning, which caused him to call the police

Miss Symonds is said to have been heard screaming at Mr Johnson to get out of the flat in a Victorian House in Camberwell, south London that she bought last year and lives in with her lover (pictured)

Both are playwrights and Ms Leigh, described as a New York-born ‘Leftist’, once gleefully boasted on Twitter that she had given Boris ‘the finger’.
She also said on social media that ‘all Tories suck’.
The 34-year-old had a leading role in a theatre project called Brexit Stage Left – a festival of plays held in January and partly funded from a £1 billion EU cultural project.
Did the couple record the bust-up, then, because they hoped to inflict on the Boris bandwagon a damaging blow? No, says Mr Penn.
The truth was they were genuinely concerned that something ‘dangerous’ might be happening in the flat.
In fairness to him, it did sound quite a quarrel.
Another neighbour said she had ‘never heard anything like it’.
But as it transpired, there was nothing sinister unfolding inside the Symonds-Johnson first-floor flat in Camberwell, South East London.
And certainly by the time police arrived, peace had been restored. Joking ensued. All was well.
But the brief episode, which also reflects, perhaps, our poisonous political times, does raise questions.
Most curious of all is what the couple did – and why they did it – after they were assured by police that there was nothing to worry about, that no one was hurt, no crime had been committed and that there was no cause for further action.
At this point many in their position might have slunk away, faintly embarrassed they had dropped their neighbours (with whom they share a tiny communal landing) in it with police.
Yet instead of letting the matter rest, Mr Penn rang The Guardian.
Not just to tip off the paper, but to tell his story, a detailed account of the night’s events.
Were the couple hoping to make a few quid?
Hardly. The Guardian doesn’t normally engage in cheque book journalism and, in any case, they don’t appear hard-up.

Speaking at a hustings in Birmingham on Saturday, Boris Johnson did not mention the issue in his opening comments, insisting: ‘We need to get Brexit done… and I am the right man’

Ms Leigh was raised in a £15 million New York home and her father was American composer Mitch Leigh who wrote the 1965 Broadway musical Man Of La Mancha, which included the huge hit The Impossible Dream.
According to Mr Penn, they rang the paper because the matter was of ‘important public interest’.
The unfortunate events might possibly never have happened were it not for Mr Johnson’s runaway success in the Tory leadership race.
On Thursday, he saw off arch rival Michael Gove to leave him facing Jeremy Hunt, over whom he has a commanding lead.
Might he have allowed a night off from his alcohol-free diet to celebrate? It would seem so.
A loud altercation – involving red wine – between Mr Johnson and Miss Symonds could be heard coming from their flat after midnight.
According to The Guardian, which has listened to the recording, Mr Johnson was heard refusing to leave the flat and telling his girlfriend ‘to get off my f****** laptop before a loud crashing noise.
The paper claimed that Symonds then said Johnson had ruined the sofa with red wine.
‘You just don’t care for anything because you are spoilt. You have no care for money or anything.’
Friends of Mr Johnson and Ms Symonds told The Mail on Sunday the laptop was being used to search the internet for solutions to remove wine stains from upholstery.
At first Mr Penn and Ms Leigh weren’t named by The Guardian, which initially tried to disguise Mr Penn’s gender, though gave it away.
The paper reported that the couple called police as a last resort after receiving no response from inside the flat.
It quoted Mr Penn, who was waiting for a takeaway, as saying: ‘I’d heard the screaming and shouting that sounded like it was from the street before I went to get my food.
‘It became clear as I returned that it was coming from inside.’
The recording, he said, was made ‘purely out of instinct’.
He added: ‘I had my phone on me because I’d gone to pick up a Deliveroo so I was on the phone to the Deliveroo driver.
‘If I saw someone who I thought was in danger on the street I would start filming while seeking help.
‘I was inside my own flat hearing shouting, screaming and banging so I pressed record.

Boris Johnson attended the Uxbridge and South Ruislip Conservative Association Summer Drinks in Uxbridge just an hour after reports of the blazing bust-up between him and his partner

Mr Johnson attended the the Uxbridge & South Ruislip Conservative Association summer drinks this evening, an hour after reports of the row with Miss Symonds emerged
‘It felt like if there was something dangerous happening that having a recording of it would be important as evidence.
‘The screaming maxed out the volume of the microphone on my phone through two doors, which is why we became concerned.’
After the couple dialled 999, police in two cars and a van arrived in minutes, but left after receiving assurances the altercation was over.
The Mail on Sunday understands that one officer even joked that the couple had done well to remove the wine stain.
Yesterday, an ally of Mr Johnson claimed ‘the police had their time wasted and they knew it at the time’.
Former leadership candidate James Cleverly said ‘the big element of the Boris story isn’t that they had a heated argument, it’s that the police were called by the same person who recorded Boris and gave the story to The Guardian’.
Another neighbour in the building said: ‘It concerns us that someone inside the house has been recording things.
‘I am sorry Boris and Carrie have had to put up with this nonsense.’
Last night, a friend of Mr Johnson and Ms Symonds said: ‘Carrie really doesn’t feel safe in her own home anymore with anti-Boris leaflets and posters stuck up on the road, hand-delivered hate mail and now her private conversations being taped through the walls.’
Not only did the couple record the altercation, it also emerged yesterday that they took the trouble to record police officers at the scene – and take down the registration numbers of their cars, all of which they passed to The Guardian.
The paper reported: ‘When police attended the scene, an officer could be heard on the radio asking a colleague to ‘restrict it’.’
In his statement last night, Mr Penn said: ‘In the early hours of Friday morning, I answered a phone call from a take-away food delivery driver. At the same time, I heard what sounded like shouting coming from the street. I went downstairs, on the phone to the driver, and collected my food.
‘On the way back into my flat, it became clear that the shouting was coming from a neighbour’s flat.

Speaking at a hustings in Birmingham today, Boris Johnson did not mention the issue in his opening comments, insisting: ‘We need to get Brexit done… and I am the right man.’

At one point Mr Johnson asked how long he had left on stage, joking: ‘There’s some quite hostile bowling.’
‘It was loud enough and angry enough that I felt frightened and concerned for the welfare of those involved, so I went inside my own home, closed the door, and pressed record on the voice memos app on my phone.
‘After a loud scream and banging, followed by silence, I ran upstairs, and with my wife agreed that we should check on our neighbours. I knocked three times at their front door, but there was no response.
‘I went back upstairs into my flat, and we agreed that we should call the police.
‘The police arrived within five minutes. Our call was made anonymously, and no names were given to the police.
‘They called back to thank us for reporting, and to let us know that nobody was harmed.
‘Once clear that no one was harmed, I contacted The Guardian, as I felt it was of important public interest. I, along with a lot of my neighbours across London, voted to remain within the EU. That is the extent of my involvement in politics.’
What the neighbours heard: How the blazing plate-smashing row between Boris and his younger girlfriend unfolded
News of the row at Ms Symonds’ flat emerged last night, after a neighbour handed a recording of the altercation to the Guardian newspaper. In the recording Mr Johnson can be heard shouting ‘get off my f***ing laptop’ before a loud crashing noise is heard.
The couple were recorded by neighbours having a ‘plate-smashing, screaming row’ during which Miss Symonds demanded he leave. Police were called, but no formal action was taken.
It followed reports Miss Symonds screamed ‘get off me’ and ‘get out of my flat’ during a terrifying bust-up with Mr Johnson in the early hours of Friday morning at her flat in Camberwell, south London.

Tom Penn, 29, who has lived at the flat in Camberwell, south London (pictured, Mr Johnson leaving the flat yesterday morning), for over a year, said he wanted to explain his reasons for recording the argument and calling the police
Next-door neighbour, 32-year-old nursery worker Fatimah, was among those who heard the loud dispute. She said: ‘There was a lot of shouting, a lady was screaming and I could hear glasses or plates being thrown quite a few times.
‘The man was shouting back. I could hear it through my walls. I was watching TV and muted it because I was so worried. It lasted for about ten minutes. I have never heard anything like that before.
‘You could hear glass being smashed and other things. It was obvious the lady was angry, she was screaming hysterically. My walls were shaking from all the noise and things that were being thrown around.’
And Earl McDermott, who lives nearby, told MailOnline: ‘It was a proper tear up. Glasses being smashed, screaming and a lot of arguing. I was walking past Johnson’s house and you could hear it coming from the top floor. I thought someone was being murdered.’

In the recording of their argument, Miss Symonds, who Mr Johnson is said to be hoping to marry after he left his second wife, was heard complaining that he had spilled red wine on her sofa. She then said: ‘You just don’t care for anything because you’re spoilt. You have no care for money or anything.’
The neighbour who took the recording, told the Guardian: ‘There was a smashing sound of what sounded like plates. There was a couple of very loud screams that I’m certain were Carrie and she was shouting to ”get out” a lot.
‘She was saying, ”get out of my flat” and he was saying no. And then there was silence after the screaming. My partner, who was in bed half asleep, had heard a loud bang and the house shook.

Boris Johnson gave a thumbs up during a visit to Nash’s Bakery in Bicester, Oxfordshire, after police were called to the home of his girlfriend Carrie Symonds in Camberwell, south London on Friday night
‘I [was] hoping that someone would answer the door and say ”We’re okay”. I knocked three times and no one came to the door.’ That neighbour called the police.
Nursery worker Fatimah, who described ‘glass being smashed’ in the property, said: ‘I have a four year old son and I was worried the noise would wake him up.
‘He had a much calmer voice and he was just telling her to calm down, but she was still chucking things about.’

She added: ‘I didn’t call the police because the police arrived like a few minutes after. I saw a police van and a police car turn up. I knew they would probably deal with the situation.
‘It went on for just over ten minutes. His voice was quite quiet but her voice was more loud. I couldn’t make out what she was saying because she was just very, very angry.’
She said she was unsure who called police.
Her husband, Imran, 33, said his wife had been frightened by the commotion.

Next-door neighbour, 32-year-old nursery worker Fatimah, was among those who heard the loud dispute. Her husband Imran (pictured today), 33, said his wife had been frightened by the commotion. He said: ‘She heard lots of shouting and screaming and something being smashed and broken’
Speaking outside the home this morning, he said: ‘I wasn’t at home, but my missus heard stuff.
‘She said she heard lots of shouting and screaming and some things being smashed or broken.’
Asked how he felt about the incident, he said: ‘It’s no big deal for me – we’re all human’.
One neighbour told the Telegraph: ‘I heard the row, it was pretty loud. I was quite worried to be honest, it was bad.
‘I heard a lot of smashing – it sounded like plates or glasses – and I could hear her shouting. It was definitely her, I didn’t hear him. There was a lot of shouting and swearing. It didn’t last that long, maybe five minutes. It was unusual because it’s very quiet around here. We don’t usually here things like this.’
Two police cars and a van arrived within minutes, shortly after midnight, but left after receiving reassurances from both the individuals in the flat that they were ‘safe and well’.
Neighbours told the Times they had not even realised that Mr Johnson had been living in the apartment until earlier this week.
One said: ‘Boris has been visiting for six to nine months. I think he lives there now because of the frequency we see him. He leaves the house about 8am and he gets picked up by his minders.’
Mr Johnson was caught out as the words used by Ms Symonds – ‘get off me’ and ‘get out of my flat’ – were picked up on a neighbour’s phone.
In a statement, Scotland Yard confirmed they were called to Miss Symonds’s flat at 24 minutes past midnight. It went on: ‘The caller was concerned for the welfare of a female neighbour. Police attended and spoke to all occupants of the address, who were all safe and well.
‘There were no offences or concerns apparent to the officers and there was no cause for police action.’
