A man has died after running on to a railway line during a police chase in London.
The incident took place after officers attempted to stop a black Audi on Powder Mill Lane in Twickenham just after midnight on Tuesday.
The car did not stop and in the ensuing chase a man, understood to be in his 30s, got out of the car and ran onto the railway line in Hounslow.
An ambulance was called but he was pronounced dead at 12.22am. His next of kin have been notified.
The police watchdog, the Independent Office for Police Conduct (IOPC), is investigating what happened.
IOPC regional director Sal Naseem said: “My thoughts are with the man’s family and friends, and those officers involved in this tragic incident.
“We are making contact with the man’s family to provide them with support and to explain our role investigating the circumstances leading up to his death.
“We sent our investigators to the scene and to the post incident procedures to begin gathering evidence.
“When someone dies following police contact, it is mandatory for forces to make a referral to the IOPC.
“Our role is to establish the circumstances of the incident and this work is already under way.”
