Police are looking four men suspected of being involved in a hit-and-run in which a cyclist was killed.
Andell Goulbourne, 59, was hit by a grey BMW M135i as he was cycling along Washwood Heath Road in the Saltley area of Birmingham at 11.15pm on Thursday 30 July.
On Saturday, West Midlands police issued CCTV images of the four occupants of the car who fled the scene on foot. The car was later seized and a 32-year-old man arrested on suspicion of causing death by dangerous driving. He was later released while inquiries continued, the force said.
DS Paul Hughes, from the force’s serious collision unit, said: “The victim, Mr Goulbourne, was callously left in the road, fatally injured, while four men ran from the vehicle.
“The offenders were more concerned about looking after themselves than calling for an ambulance or trying to help the man they’d hit.
“It’s now almost three weeks since the collision and I would urge the men caught on camera to do the right thing and come and talk to us.”
The family of Goulbourne, a father of three, said in a statement: “Andell was a kind and generous individual, a mentor to many young people.
“He always sought to serve those less fortunate; this was reflected in his role as a volunteer charity worker. He was a beacon of light.
“Our family and the black community are desperately appealing to you to come forward. This was a cruel and heartless act.”
Anyone with any information is asked to contact West Midlands police.
