DETECTIVES have issued CCTV footage of nine vehicles that drove past a 20-year-old man who was later found with serious head injuries in Farnham on Boxing Day.

Aidan Warner, who is still in a coma at St George’s Hospital in Tooting, was found lying in Upper Hale Road, close to Queens Lane, with serious head injuries at 7.27pm after a night out with friends.

At 7.25pm, he had left the Upper Hale Working Men’s Club, a short walk from where he was found on the section of the road which has no pavement.

CCTV footage shows that nine vehicles travelled up and down Upper Hale Road between when the victim left the club and when he was found.

The vehicles can be seen in the video online at youtu.be/VWG8Hb3d4vk.

Investigating officer Detective Constable Will Marsh said: "This has been an incredibly distressing time for the family who are understandably keen to find out what happened to their son.

"We are still keeping an open mind about what happened but cannot rule out that it involved a car, or it might be that he was assaulted.

"We are continuing to appeal for anyone who has any knowledge of what happened to get in touch with us. If you recognise the cars pictured and think you might have been involved, know who was, or saw what happened that night, please get in touch with us.

"If you don’t want to report any information to a police officer you can report it anonymously to the independent charity Crimestoppers by calling 0800 555111.”
