Police from the Road Death Investigation Unit in Catford have appealed for a cyclist involved in a crash with a pedestrian to come forward as a witness. They have released CCTV images of the cyclist taken moments after the crash.

David Purkiss aged 58 from West Wickham died of a stroke two days after the crash in Regent Street on Thursday 25th July. The police report that: "Initially both parties appeared uninjured and having spoken with each other at the scene they then carried on their journeys."

The police are asking for the cyclist and anyone else who witnessed the crash to contact them on 020 8285 1574. Following a post-mortem examination on 9th August the police "await the result of further tests" to determine if there is a link between the crash and Mr Purkiss' death.

LCC Campaigns Officer Charlie Lloyd said "Our deepest sympathies go out to Mr Purkiss' wife and children. We fully support the police call for the cycilst involved and other witnesses to come forward and help them understand what happened."

He added, "Cyclists should always take great care to ensure the safety of pedestrians crossing the road."
