The brother of a prominent bikie who was found dead in a dog park was ‘too pure of heart for this cruel world’, his former girlfriend said. 

Harrison ‘Harry’ Geppert, 17, died of stabbing injuries on Wednesday night and a man, 18, handed himself in to police this morning. 

Harry’s ex-lover Kahlia Kingi today paid tribute to her former flame, as the victim’s brother and his business partner issued chilling warnings.  

Prior to police making the arrest, former Hells Angels enforcer Ben Geppert said: ‘I won’t rest until I have made this person pay’. 

Meanwhile, Forrest Gamble, who runs a clothing brand with Ben, warned: ‘Hope the cops find you first’.

Ben said on Thursday morning that he was ‘crushed’ and ‘if I could give my life for you to have yours back I would do so without thinking twice’. 

Miss Kingi – who dated Harry for a few years and went to school with him – joined the tributes in a statement to Daily Mail Australia.   

‘Words can’t describe the pain I’m feeling right now,’ she said. 

‘Harry you were such a big part of my life and so many others. 

‘You had such a big beautiful heart too pure for this cruel world I’m never going to forget your cheeky smile and the happiness you brought me!! 

Fly high Harry I’ll never forget you.’ 

Her brother was meant to meet up with Harry on the weekend – but that will tragically never happen.

Ben told his Instagram followers he was ‘crushed and heartbroken’ at his brother’s death and hinted he was thirsty for blood. 

In a moving post, he wrote: ‘Rest in paradise Harry Geppert, I love you my little brother! I love you more than anything regardless of the things that have gone on in our family.’

In a separate post, the ex-bikie said he wished he ‘could have been there to help’ his brother.

‘I would have never let this happen, RIP my brother I love you. I won’t stop until I sort this Harry I promise you,’ he wrote.

He posted to his Instagram story: ‘Nothing compares to the feeling of losing my little brother.’

Loving friends of the 17-year-old also flooded social media with their messages of love and affection for him.

‘Rest in peace to one of the most beautiful, happy, and entertaining souls that lived throughout our day and age,’ one friend wrote to Facebook.

Antonio Gatt told Daily Mail Australia his friend was a ‘loving and caring boy’ who always knew ‘where and who to go to for help’.

‘As brothers we loved him, as family we loved him. If we could take back time, we would only take back 24 hours because he lived up to his standard until the very end.

‘Never below us, never on top always beside. Never forgotten! Rest easy and so much love.’

According to the Gold Coast Bulletin, police are looking into whether the stabbing was the result of an ongoing feud between a group of teenagers. 

Acting Detective Superintendent Brendan Smith is urging anyone who may have seen something suspicious to come forward.

‘We are keen to talk to anyone who was in the area at the time. Particularly anyone who may have been walking their dog or cars going past with dashcams,’ he told reporters on Wednesday evening.

‘It is unclear at the point what the cause of death is but it certainly looks like it is suspicious.

‘There’s conflicting versions how he got there and where he came from. So at this point it would be too early to say what happened.’

Police spent much of Wednesday evening on the scene attempting to piece together what had happened.

A crime scene was established and the area was cordoned off, as police spoke to residents in the area to try and get information. 

On Monday, Geppert unveiled a new fashion label he hopes will help turn young people away from a life of crime.

The clothing line has been in the works for two years and is a collaboration between Geppert and his friend Forrest Gamble.

‘You want to influence the younger people that are growing up around that lifestyle I grew up in,’ Geppert told Nine News.

Speaking from his own experience, Geppert said he had chosen to leave the outlaw bikie gang because he didn’t want to die.

‘There’s only two places that you end up, and that’s in a grave or jail,’ he said.

Geppert is a well-known identity in the bikie underworld. He regularly posts to Instagram and has more than 11,000 followers.

He made headlines in May last year after he was filmed exchanging blows with a bikie rival in front of a Gold Coast KFC.

Following the on-camera scuffle, Geppert was given a six-month prison sentence, suspended for three years.

Earlier this year, Geppert was confronted by men in a Gold Coast shopping centre and refused to fight them.

The men filmed themselves trying to taunt a disinterested Geppert into brawling with them, while hurling abuse.

‘I’m not going to jail over you,’ Geppert said while walking away.

Then in April, Geppert took to Instagram to tell his followers that he was ditching his ‘gangster life’.

Geppert says he chose to leave behind the chapter due to disagreements.

‘At the time there was personal things going down in the club internally, I just didn’t agree with it at the time,’ he said.

Geppert insists his time with the bikie gang is in the past and he now looks to a new, different future.

‘We’ve all done some bad things in our lives and I suppose it just follows us forever, but at the same time, you know, we all deserve a second chance.’
