A watchdog has launched an investigation after the death of a motorcyclist whose bike was hit by a Range Rover that had failed to stop for police.

The rider was killed on the A3 near Putney Common, Wandsworth, in the early hours of Monday after the crash with the 4×4.

The Independent Office for Police Conduct (IOPC) said the Range Rover failed to stop for police at around 12.30am, sparking a chase before it hit the motorbike and overturned.
