The family of a knife crime victim who was a childhood friend of grime artist Stormzy have made an emotional appeal for information to help bring his killers to justice.

Police have revealed CCTV footage  on the second anniversary of 23-year-old Bjorn Brown’s murder. Bjorn,  a nephew of a former Gogglebox star Sandi Bogle, was knifed in March 2017 and tried to cycle to a nearby hospital before collapsing dying less than a week later on April 3.

A £20,000 reward is also being offered for information on the father-of-one’s death. His aunt Sandi , who has also appeared on Celebrity Big Brother,  described knife crime as “an epidemic”, while Mr Brown’s mother Maxine Brown said it is “killing off” the next generation.

Ms Brown said: “Children are still dying two years on. It’s killing them (the next generation) off. There ain’t gonna be a next generation if this carries on.”

Ms Bogle said: “He used to go to the studio with Stormzy, they grew up together, Stormzy knew him well.”

She said the Thornton Heath star had been supportive of the family’s campaign for justice, including tweeting after the death and holding a minute’s silence at one of his concerts.

She added: “It has been two years since Bjorn was suddenly and tragically murdered – his life has been taken away but his killers are still out on streets.“This attack did not happen in the middle of the night or on a deserted street. We know people were in the area at the time and we are urging them to get in touch – it is never too late.

“We continue to grieve for our son, nephew and brother. Nothing will ever bring him back, but we hope that someone, somewhere will find the courage to come forward and help us get the justice we need.”

The CCTV footage  of the moments leading up to and after the stabbing  shows two male suspects alongside Bjorn – who was on his bike – on Bensham Lane, just past the junction with Kelling Gardens at around 20:33pm on 29 March 2017.

The three then turn back on themselves and go into Kelling Gardens, which is where Bjorn is believed to have been stabbed. Moments later, the two suspects run back out onto Bensham Lane, followed shortly afterwards by Bjorn on his bike.

It is believed Bjorn was attempting to cycle to a nearby hospital but he collapsed further up the road and was assisted by a member of the public driving past who called an ambulance. 

A post-mortem examination confirmed Bjorn’s death was the result of a stab injury.

Detective Sergeant Andy Sheppard, from the Met’s Homicide and Major Crime Command, said: “We are continuing to appeal for any information which can help us find those responsible for Bjorn’s death.

“The motive for this fatal attack remains unclear, but we do know that in the two years that have passed, allegiances may have changed and someone who was unwilling to speak out at the time may now feel in a position to come forward.

“We are also appealing for anyone who thinks they may know the two individuals seen in this CCTV footage to get in touch with any information which could help identify them.

“Our officers are working tirelessly to get justice for Bjorn and bring some closure for his family. We will continue to do all we can to solve this murder.”
