POLICE have renewed their appeal for witnesses to come forward after a cyclist who suffered head injuries in a collision on the A38 died yesterday.

The 72-year-old man, who has not been named, died of his injuries at Frenchay Hospital, 11 days after falling from his bike in the accident at Buckover.

He had been taking part in a Lands End to John O'Groats sponsored ride when the accident happened shortly after 8am on Saturday, June 9.

The man was in a critical but stable condition but died on Wednesday, June 20.

A police spokesman said: "He was discovered by members of the public with serious head injuries and taken to Frenchay Hospital in a critical condition but died yesterday.

"Police are keen to trace any witnesses, who may have been in the area at the time of the incident, who could have useful information to help their inquiries. They would particularly like to hear from anyone who may have seen the cyclist earlier that morning."

Officers have been investigating whether the cyclist was blown by a gust of wind or whether he was knocked off his bike unknowingly by a passing vehicle.

Anyone with any information is asked to contact the collision investigation unit on the force number 101.
