A SENIOR detective has told revellers to "just walk away" if faced with an argument on a night out after a man was convicted of killing a father in a one-punch attack.

Just after midnight on Wednesday, August 19 last year, two groups in Vineyard Street car park became involved in an argument after an evening out in Colchester town centre, which quickly escalated to violence.

CCTV showed that during the incident, Steven Warburton, 46, leant down to help his wife, who had been knocked to the floor during the scuffle.

While doing so, he was punched by a member of the second group, causing him to fall backwards with force and hit his head against the pavement.

When officers arrived, Steve was found unconscious in the car park. The second group had already left the scene in their car.

Steve was taken to hospital in a life-threatening condition and died of his injuries three and a half weeks later.

A forensic post-mortem examination found he had suffered a traumatic brain injury.

Brodie Groome, 27, of Sydney Street, Brightlingsea, was initially charged with causing grievous bodily harm with intent.

At Ipswich Crown Court on October 2 last year, the charge was amended to manslaughter.

Throughout the investigation, Groome claimed that he acted in self-defence.

He stood trial at Ipswich Crown Court and on Thursday a jury found him guilty of manslaughter. He is due to be sentenced on December 1.

Detective Chief Inspector Greg Wood, senior investigating officer, said: "Everyone should be able to enjoy an evening out with their friends and loved ones, and get home safely.

“Steven’s death was completely avoidable and this case highlights just how quickly a situation can escalate.

“If you or your friend get into an argument on a night out, particularly if you have been drinking, please don’t turn to violence. Just walk away.

“A single act of aggression can easily result in serious injury, or as with this case, someone’s tragic death.

“Nothing good will come out of it.”
