Police are searching for new witnesses after a fatal “hit-and-run” crash in Harrow more than 18 months ago.

Ping Leung Cheng, also known as Colin, was found injured by a member of the public at the junction between St Andrews Close and Culver Grove just after midnight on August 7, 2022.

The 61-year-old died at the scene, and officers found that he had injuries consistent with being hit by a car.

The driver of the car, believed to be a silver Mercedes, did not stop at the scene of the crash.

Police have now urged witnesses who have not already come forward to get in touch, as his family paid tribute to the “hardworking” man they knew.

Colin’s family added: "Colin was a beloved member of our family and of the community.

“He never failed to celebrate life's important milestones within our family and always made every effort to be present at them.

"Cooking was his passion and he always used it as a way to bless those around him, whether it was turning up with our favourite dishes or hosting a big party.

"Those who crossed paths with Colin will also tell you that he was one of the most hardworking people you'll ever meet - whether it was maintaining his home and garden or at his job in Nando's, his character and person always brought a smile to your face."

In January last year, a 29-year-old man was arrested on suspicion of causing death by dangerous driving and failing to stop after a collision.

He has been released under investigation while enquiries continue.

Detective Sergeant Rebecca Collens, from the serious collision investigation team, said: "I know some time has passed since the incident occurred, but Colin's family are desperate to know what happened to him and they deserve answers.

"I'd ask anyone with information about the collision, or saw the car in the area, to come forward immediately."

Anyone with information that could help the investigation is asked to call detectives on 020 8246 9820.
