The fatal stabbing of a man inside his car in a busy area of London was a targeted attack, Scotland Yard said.

Police were called at 2.37pm on March 29 after reports of a stabbing on Clapham Park Road, close to Clapham Common tube station.

A 40-year-old man was found suffering from stab wounds and died at the scene.

Detective Chief Inspector Paul Healy, who is leading the investigation, said: "This was a vicious and targeted attack on a man inside his car in a busy area.

"We understand the victim was driving a black VW Golf that was turning right from Clapham High Street onto Clapham Park Road when he was set upon by a group of males whilst sat inside his car.

"He received fatal injuries. The suspects, officers are working to trace are three males all of slim build seen leaving the area immediately after the attack.

"If you saw them or know who they are, I need you to get in touch with police urgently.

Chief Superintendent Simon Messinger, of the South Central Command Unit, said: "Homicide detectives do believe this was a targeted attack.

"That being said, I fully appreciate the alarm and concern this incident will raise particularly coming so soon after the fatal shooting of a young man in West Norwood.

"At this stage, there is nothing to suggest either incident is connected."

Witnesses and those with information are urged to call the Homicide and Major Crime Command Incident Room on 0208 358 0400, tweet @MetCC or Crimestoppers anonymously on 0800 555 111.
