Police want to trace a cyclist following the death of a pedestrian in Shepherd’s Bush, west London.

The cyclist was involved in a collision with a 72-year-old man in Frithville Gardens.

The man was taken to a central London hospital by the London ambulance service following the incident on 30 December but died on 15 January.

Detectives are appealing to trace the cyclist, who is described as a black male. He stopped at the scene of the collision, but as police were informed of the incident only after the pedestrian’s death, they have no record of who he is.

A police spokesman said they were told about the death on 27 January and detectives from the Metropolitan police’s serious collision investigation unit have since begun an investigation.

“It is of paramount importance that the cyclist comes forward and assists detectives with their investigation,” the spokesman added. “They would like to reassure the individual that at this stage, all they wish to do is speak with them and establish the circumstances that led to the collision.”

Given the time of day, police believe there would have been a number of people in the area. They are also appealing to anyone who saw the collision to come forward. Anyone who has any information is asked to contact the unit on 020 8543 5157 or via Twitter.
