Detectives have released footage of a man they want to trace in connection with the fatal shooting of Jason Diallo in Ilford four years ago and issued a £20,000 reward.
Investigators are hunting two men they believe were involved in the shootings while two are already in jail.
Father of two Mr Diallo, 30, was cycling in Balfour Road, Ilford, when a car knocked him off his bike and two men got out of the vehicle and shot him in the head. He died at the scene after the attack at around 10.15pm on 1 November 2020.
Just 15 minutes later around five miles away a second man, 27, was shot in the shoulder in Garvary Road.
He was taken to hospital with gunshot wounds which were not life-threatening. The victim told officers had been followed by three men driving a car who began shooting at him.
Mushin Mohamed, 28, of Leytonstone Road, was found guilty of murder and attempted murder at the Old Bailey and sentenced to life in prison to serve a minimum of 35 years in 2022. Tyrelle Joseph, 24, of Banks Way, was found guilty of assisting an offender and jailed for seven years.
Enquiries have remained ongoing to identify two more suspects believed to be involved in the shootings and police are offering a reward of up to £20,000 to bring them to justice.
A video clip of a man they want to trace has been released in the hope that people with information will come forward to identify him.
Detective Chief Inspector Kelly Allen, the senior investigating officer, said: “We have continued our momentum behind this investigation to ensure that those responsible for killing Jason Diallo and seriously injuring another man are held accountable.
“Our enquiries have found no evidence to suggest that Jason Diallo or the attempted murder victim were known to one another or those convicted, suggesting that this was a completely unprovoked and violent incident.
“Jason Diallo was described by his family as a devoted father of two who had the softest heart. Our thoughts have remained with his family and friends throughout a difficult four years and we are determined that they see justice.
“We are now in a position to release an image of this man, who we would like to speak with in connection with this ongoing investigation.
“If you know who he is or have any information which could help us, please get in contact.”
Anyone with information is asked to call 101 quoting Operation Shenley. You can also report information anonymously to Crimestoppers by calling 0800 555 111.
