Detectives are renewing appeals following a fatal collision and have released an image of a possible witness they wish to identify.
Police were called at 00:27hrs on Saturday, 10 November to Hampton Court Road, near the Esso petrol garage, following reports of a vehicle in a collision with a pedestrian.
Officers attended with colleagues from the London Ambulance Service (LAS).
A 50-year-old man was discovered suffering from serious injuries. Sadly he was pronounced dead at the scene.
He has been named as Jonathan Treleaven. His next of kin have been informed.
Detectives from the Serious Collision Investigation Unit are keen to trace any witnesses who may have seen the collision or the immediate aftermath.
In particular, officers are trying to trace a witness - who is believed to be a taxi driver - who filled up with petrol at the Esso petrol garage just prior to the collision. He is believed to have been driving a blue Toyota Auris.
Mr Treleaven's family described him as a much loved family man who will be very sorely missed. They said: "We are desperate for answers and for the public to assist officers in their enquiries."
His co-workers said he was a "respected colleague and friend who will be sorely missed."
Anyone with information that may assist police is asked to call DC Moon or DC Price at the Serious Collision Investigation Unit on 020 8543 5157, or via 101 quoting CAD 140/10Nov.
