A man shot dead close to a funeral appears to have been an innocent bystander, Scotland Yard said.
Azezur Khan, 21, was gunned down in East Dulwich, south-east London, last Thursday after attending the service.
Mr Khan, known as Ronnie, was shot near the junction of Forest Hill Road and Rockells Place at around 3pm on November 3.
A Metropolitan Police spokesman said: "Detectives believe Ronnie may have been an innocent bystander in the shooting and they have no information to suggest, at this stage, as to why he would have been shot."
He was declared dead at the scene, and a post-mortem examination gave the cause of death as a single gunshot wound to the abdomen.
A 17-year-old boy remains in a stable condition in hospital after he was shot in the ankle.
Two 17-year-old girls and two 20-year-old men were arrested over the incident and were bailed to late November.
Several shots were fired shortly after mourners left the funeral of 17-year-old road crash victim Joel James Lee Morgan at the nearby cemetery. Detectives said at least 50 people attended the service, including both shooting victims.
Two males are being sought over the attacks, one of whom was carrying a gun.
Last week, Detective Superintendent Gordon Allison, of Operation Trident, said the boy whose funeral it was had "contact with gang members". But he added that police were keeping "a very open mind" about the motive for the attack.
