The police officer assisting at the scene of an accident did not contribute to the death of Slough teacher Ahmed Bafadhel an investigation has decided.

Mr Bafadhel, 28, of Alpha Street, Slough died after his Honda motorbike collided with a second motorbike and a Mercedes car on the A355 Amersham Road near Amersham on Sunday, July 31 last year.

The teacher was airlifted to the John Radcliffe Hospital in Oxford but staff could not save him.

Mr Bafadhel was head of technology at Slough and Eton School and a member of the Deen Riders, a Muslim motorbike organisation that works with charities around the world.

He was also the carer and main support network for his elderly parents and provided bike safety classes to pupils at school.

The second rider, Babar Gull from Wooburn Green was later given a suspended jail sentence for causing death by careless driving.

The Independent Police Complaints Commission (IPCC) later begun an investigation into the actions of the police before the collision, as a Thames Valley police vehicle was at the scene.

But over a year later the officer PC Matthew Carson - who had stopped to help the driver of a broken down Mercedes on the crest of a hill on the A355 between Amersham and Beaconsfield - has been cleared of any blame.

He positioned his car behind the Mercedes and activated his lights to act as a warning before directing traffic round the car was partially blocking a lane. The two motorcyclists crashed as they attempted to brake and avoid stationary traffic queuing to use the single available lane.

The investigation found no indication that the actions of PC Carson fell below the standard of professional behaviour or caused or contributed to the death of Mr Bafadhel.

Publication of the report was delayed until after criminal proceedings surrounding the crash were completed.

IPCC associate commissioner Guido Liguori said: “The death of Mr Bafadhel was a tragic accident and my thoughts are with his family and friends, and all those affected by this terrible incident."
