A probe into police conduct has been launched after a man was killed in a motorcycle pile-up on a country road near Coleshill in Buckinghamshire. The motorcyclist was killed in the crash along the A355 Amersham Road on Sunday (31 July) at 12.20pm in a collision that left several other motorcyclists injured.

Thames Valley Police were already at the scene of the incident when the crash happened and the Independent Police Complaints Commission has launched an inquiry into their post-crash procedures.

"As police were present at the scene at the time, the IPCC was notified of the incident by Thames Valley Police and deployed an investigator to the police post-incident procedures," a statement from the police watchdog said.

"The IPCC has since decided to conduct an independent investigation into the actions of police, alongside an investigation into the collision by a specialist unit from Hertfordshire Constabulary."

Some witnesses at the scene of yesterday's crash have already been spoken to, but investigators want to speak to any further witnesses who may have been travelling on the Amersham Road at that time and especially those who may have seen the crash.

Witnesses are being asked to contact the IPCC on 0800 096 9070 or email witness@ipcc.gsi.gov.uk.

Since 2014, five people have been killed in collisions along the stretch of road, which runs between Beaconsfield and Amersham.
