Debra Mackrell, 43, pictured, is accused of stalking and harassing ex-boyfriend and fellow police officer Paul Brewster after becoming convinced he was having an affair before they broke up in 2016

A police officer is accused of stalking her ex-boyfriend and ‘bombarding’ him with thousands of calls and texts and ‘threatening to derail his career as a firearms officer’ after ‘becoming convinced he had cheated on her with a colleague’.

Debra Mackrell, 43, allegedly made 1,600 anonymous calls to Paul Brewster following their break-up in 2016 along with thousands of texts which continued even after he ‘begged her to stop’. 

Inner London Crown Court also heard she threatened to tell his superiors in the SO19 firearms unit he was ‘mentally unfit to handle a gun’ to get him kicked out.

She was also arrested while awaiting trial after allegedly sending Mr Brewster an unwanted brochure for holidays in Cyprus to ‘remind him she was still there’.   

Jurors were told ‘possessive’ Mackrell, of Milton Keynes, accused Mr Brewster of having an affair with colleague Jenny Devine at Hackney Borough police station before ‘switching her fixation’ to custody officer Genevieve Pereira.   

David Povall, prosecuting, claimed her behaviour showed ‘a degree of obsession.’

He said: ‘She stalked, harassed her ex-partner over a period of months by bombarding him with messages, by making nuisance phone calls, by turning up at his place of work and travelling home with him, ultimately by sending him unwanted post while she was awaiting trial for this case.

‘One of the things that contributed to the end of that relationship was that Paul Brewster found that Debra Mackrell is very possessive and very jealous, she accused him of carrying on an affair with another officer Jenny Devine.’

The court heard after their break-up there was initially little contact until Mackrell started sending messages when Mr Brewster stopped working in Hackney Borough and moved to the SO19 firearms team. 

Mr Povall said: ‘She was suggesting that he was now in a relationship with the female custody officer who worked at Hackney Borough by the name Genevieve Pereira.

‘He said he was not but she did not believe him and over a period of months, leading up to June 2016, there were text exchanges between them – not every day but consistently and regularly – during which she refused to accept he was not in a relationship with her, during which she abused him and suggested that this was an affront to her, and during which she abused Genevieve Pereira.’

She was then accused of making threats to ruin Mr Brewster’s career as a firearms officer.

Mr Povall continued: ‘He received sometimes dozens or hundreds of calls in a day. He would leave work on occasions and finds that she was there waiting for him or she would follow him and join him as he was walking home – it was something he found unnerving.

‘The messages to him were starting to escalate to threats that she would take action to damage his career and go to the Directorate of Professional Standards and suggest that he was not mentally fit for carrying firearms.’

A court heard Mackrell believed Mr Brewster had been seeing two colleagues at Hackney police station, pictured 

Mr Povall showed the jury sample pages of text messages where Mackrell continuously contacted Mr Brewster over a period of 12 hours – even continuing when he begged her not to.

It was only after her arrest on October 6, 2017, that the extent of her communication came to light.

The court heard two of her phones seized and showed she sometimes sent hundreds of texts to him each day alongside the 1,600 phone calls.

While awaiting trial she was arrested again after a brochure from a holiday company they had used as a couple was posted to Mr Brewster’s home and was traced back to her.

Mr Povall said: ‘In March 2019, once there had been no further contact and the calls had ended, he received an envelope – a large A4 envelope, and when he opened it up he found it contained a brochure was from a holiday company for holidays in Cyprus.

‘He was not on their mailing list but that was a holiday company he used with Debra Mackrell when they were in a relationship. Inquiries were made to see where that came from because it had come signed for Royal Mail Service.’

CCTV of a post office where the letter was sent from showed Mackrell with the envelope.

Mr Povall added: ‘We suggest the clear intention of that was to fly up another flag to say ‘I’m still here.’

The trial continues.
