Police probe as driver died following M4 chase crash.
AN independent investigation has been opened by the Independent Police Complaints Commission (IPCC) after a 35-year-old man died following a police pursuit on the M4 in Cardiff.
Andrew Gwynne, from Gloucester, died at the scene of the incident when a red Ford Focus he was driving crashed with a stationary Land Rover on the hard shoulder.
The incident happened at around 6pm on Saturday near the Coryton interchange at junction 32.
A spokeswoman for the IPCC said Mr Gwynne had been reported missing after concerns for his welfare were raised by his family earlier that day.
The spokeswoman said initial information shows Mr Gwynne was seen driving on the M4 and attempts were made to stop his car, including the deployment of a stinger.
The driver of the Land Rover was taken to the University Hospital of Wales, in Cardiff, after being cut free but is not believed to have been seriously injured.
IPCC investigators attended the scene on Saturday evening and a local police station. Initial accounts have been taken from the police officers involved.
The IPCC said "a significant number" of members of the public who witnessed the incident have also been identified.
IPCC operations manager Mel Palmer said: "This was a tragic event and my thoughts are with Mr Gwynne's family and friends."
A tribute released by Mr Gwynne's family yesterday described the 35-year-old as a "massive part of a large family".
