A suspect has been arrested by detectives hunting the killer of a hard-working father-of-five shot dead trying to flee his black BMW car in Chingford, East London.
Wayne Powell, 39, (pictured) from Tottenham, North London suffered fatal multiple gunshot wounds in Higham Station Avenue on July 5.
Officers and an ambulance were called at 11:14 pm and Wayne, who worked at Seven Sisters Underground Station, was rushed to the Royal London Hospital where he was pronounced dead.
A post-mortem gave cause of death as gunshot wounds.
An incident room has opened under Detective Chief Inspector John Crossley from Operation Trident, which investigates violent black-on-black crime.
DCI Crossley said: "We are looking for a lone gunman who was wearing dark clothing. The suspect is believed to have left the scene of the shooting along a footpath in the direction of Coningsby Gardens.
"I would implore anyone who believes that they have information that could help this investigation to speak to police."
