Cyclist Hurt In Hit And Run
Police in Wareham are renewing their appeal for witnesses after a hit and run near the town.
At approximately 6.10am on Thursday 27 September 2012 a crash between a cyclist and a vehicle occurred on the A352 in East Stoke near the Stokeford Inn.
The cyclist, a local man in his thirties, was travelling in the general direction of Wareham when an unknown vehicle hit him from behind.
The driver has then left the scene without stopping, leaving the cyclist lying unconscious in the road. The victim sustained concussion and was taken to Poole Hospital.
Police Constable Gatfield, of Dorset Police Traffic Unit, said: “The road, which runs between Wool and Wareham, was surprisingly busy for this time of morning and I believe that other motorists would have seen the cyclist and possibly witnessed the collision.
“I am appealing for anyone who has witnessed the incident, has any information about the collision or saw the pedal cyclist prior to it to call police.
“I would encourage anyone with the slightest information, which may identify the driver or the vehicle, to contact Dorset Police on 101.
“I also urge the driver in question to do the right thing and speak with the police.
“All calls will be treated in the strictest of confidence.”
Witnesses and anyone with information should call Dorset Police in confidence on 101 quoting incident number 27:50. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
