A teenage boy has been found guilty of manslaughter after he stabbed a man to death in a row over a bicycle.

The 14-year-old, who cannot be named for legal reasons, attacked Darren Edginton, 39, in a secluded lane following a dispute.

The pair had become embroiled in an argument over the ownership of a 'YoBike', which are available for hire across Bristol.

He killed Mr Edgington with a single stab wound to the chest on June 21.

The teen was convicted at Bristol Crown Court today and will be sentenced on February 3.

He is one of the youngest people ever to be convicted of manslaughter in the Avon and Somerset force area.

Det Supt Julie Mackay said: "This is a tragedy for everyone involved.

"CCTV doesn't capture the moment of the stabbing but we heard testimony from the victim's friend who was at the scene.

"He heard Mr Edginton say he'd been stabbed, shortly before he staggered to nearby Ashley Road and collapsed.

"He died despite the best efforts of the members of the public and emergency services personnel who tried to save him.

"The defendant was identified as a suspect through CCTV and arrested less than 10 hours later.

"A small spot of the victim's blood was found on his trainers and analysis of his phone found he'd been making efforts to purchase knives online.

"There was no evidence to show any knife was actually purchased online.

"But we discovered video footage of a hand holding a very similar knife to one of the ones viewed online and were able to prove this was filmed in the defendant's bedroom.

"In interview, he first claimed it was a case of mistaken identity.

"But, due to the weight of evidence against him including data from his phone which placed him in the lane where the attack happened, he admitted he was the one who stabbed Mr Edginton.

"He claimed it was an accident/self-defence but the jury didn't believe his version of events and convicted him of manslaughter."

"Our thoughts go out to Darren Edginton's friends and family and I'd like to thank them and all the witnesses who gave evidence in court for their assistance in this investigation."

Ch Insp Paul Wigginton added: "I'd encourage parents to talk to their children about the dangers of carrying a knife and use this case as a real-life example of the grave implications of doing so.

"Yes, they are difficult conversations to initiate, but they are well worth having.

"The facts remain that you're more likely to be stabbed yourself if you carry a knife and if you're caught carrying a knife, or worse, if you use a knife to commit a violent act then you're putting your future prospects in jeopardy."
