Detectives investigating a murder in Fulham believe the gunman was lying in wait for the victim.
The Metropolitan Police has launched a witness appeal after a 24-year-old man was shot dead in the street in Fulham .
The Met were called to the incident at around 9.30pm on Monday December 5 following reports that shots has been fired in Walham Grove.
When officers arrived at the scene, a man was found sat in the front passenger seat of a parked car, with gunshot wounds to the head.
The victim was pronounced dead at the scene.
Detectives believe that the victim had been eating with a friend at a fast food restaurant in Walham Grove.
The pair are thought to have then returned to a silver and black Renault Captur, which was parked near to the junction of North End Road and police believe the victim was then shot as he was getting into the car.
Leader of the investigation, detective chief inspector, Noel McHugh, has said: "It would appear that the murderer had been waiting in the street in Walham Grove for a while for the friends to return to their car."
Police are also appealing for any road users who may hold vital material.
Mr McHugh said: "I am directly appealing to any cyclists or drivers who were in Walham Grove or North End Road from 8.30pm who may have captured images on their own cameras.
"This material could have captured something that may prove significant, so please get in touch with us and share your footage.
"At this stage in our investigation we are keeping an open mind regarding motive and will be trying to establish the victim's precise movements in the days running up to his murder.
"Officers have been working through the night to carry out house-to-house enquiries and capture any CCTV.
"North End Road and Walham Grove would have been busy at that time of night.
"I would like to hear from anyone who may have seen or heard something that could help us catch the person responsible for this murder."
