TRIBUTES have poured in for a Thames Valley Police constable who appeared on TV show Road Wars who was killed in a crash yesterday.

James Dixon was on duty and riding a motorbike when the accident happened on the A4, Bath Road, in Wargrave at about 1.50pm.

He collided with a car, and a 91-year-old woman who was inside also died in the incident.

PC Dixon was based at Loddon Valley police station, and the force said his family had been informed of his death.

PC Dixon had been a popular character on Sky One reality show, Road Wars.

South Central Ambulance Service, whose paramedics had worked with the constable, tweeted its sympathies.

As is standard in such circumstances, Thames Valley Police has now referred the case to the Independent Police Complaints Commission (IPCC) which has now launched an investigation.

IPCC associate commissioner Guido Liguori said: "We have been notified by Thames Valley Police of a collision on the A4 near Reading, in which, tragically, a 91 year old woman and a police officer have died.

"My thoughts and sympathies are with their families and friends and the colleagues of the officer at this very difficult time.

"IPCC investigators are attending the scene as part of an independent investigation to determine the circumstances which lead to the collision."
