Police are appealing for witnesses to a hit-and-run in Buckinghamshire that caused a motorcyclist to fracture his spine, requiring full reconstruction surgery.

Thames Valley Police is appealing for information about a hit-and-run that took place on the junction of Dukes Wood Road and Oxford Road in Gerrards Cross at around 4:30pm on Sunday, October 8.

A Harley Davidson-style motorcycle and a Triumph Bonneville 865 bike were pulling away from traffic lights at the junction when the Harley Davidson rider tried to overtake the Triumph, causing the rider of the Triumph to fall off.

The rider of the Harley Davidson did not stop at the scene and police are still working to ascertain their identity.

It was initially believed that the injured motorcyclist had dislocated his shoulder on the fall, but it has now been confirmed that he fractured his spine and has undergone full reconstruction surgery.

He has since been discharged from hospital.

Investigating officer PC Matt Sara said: “We are releasing this appeal now, as it has become apparent that the motorcyclist sustained more serious injuries than was originally thought.

“Although this collision occurred one month ago, I believe a number of people will have witnessed this incident and I am appealing to anybody who may have been driving in the area at the time and who witnessed this collision to please get in touch.

“The other rider did not stop at the scene, and it may be that he did not realise the seriousness of the collision.

“I would therefore urge this person to contact Thames Valley Police as we will need to speak to him about the incident.”

Anyone with information about the hit-and-run can make a report online or call 101, quoting reference number 43230452314.
