Detectives investigating the murder of Trevor Ellis who was shot on the night of the riots, have issued a fresh appeal for information about his death.

A £20,000 reward for information leading to the identification, arrest and prosecution of those responsible for the 26-year-olds death is still on offer.

Mr Ellis, who would have turned 29 tomorrow (Saturday), was discovered at 9.20pm in a car in Duppas Hill Road at the junction with Warrington Road, on Monday, August 8 2011.

The father-of-four was rushed to St George's Hospital suffering a gunshot wound to his head, but despite efforts by medical staff Mr Ellis from Brixton, died from his injuries the next day.

Police believe Mr Ellis travelled to Croydon with friends early on August 8, 2011. It is believed the group became involved in an altercation with another group of about nine people.

The altercation resulted in a car pursuit involving three vehicles which started in Scarbrook Road passing along the A232 flyover into Duppas Hill Road where Mr Ellis was shot.

Detective Chief Inspector Diane Tudway of the Homicide and Major Crime Command said: "I believe his killers were actively involved in looting and responsible for robbing at least two people that night.

"They thought nothing of arming themselves with a gun and ultimately taking a young man's life leaving four young children without a father.

"His family should have been with him this very weekend on Saturday, December 14, celebrating his 29th birthday. Instead they continue to mourn his loss.

"Plenty of time has past since the night Mr Ellis was killed and we know that allegiances shift. We urge anyone with information about this murder to come forward and help police."

In a statement, Mr Ellis' family said: "Trevor was a father, son, brother and a charming family member missed by all that knew him. He has been murdered needlessly with no remorse.

"Please help us bring the killers to justice with any information you may have no matter how insignificant it may seem. No one deserves in die this way."

Fourteen men arrested in connection with the investigation have all been bailed and told they face no further action.
