SURREY Police are appealing for witnesses to help piece together the movements of a man in his 50s who is in St George’s Hospital in Tooting with serious head injuries.

The man is described as being around 5ft 7ins tall, of medium build and having greying hair which is usually tied into a ponytail. He was wearing a yellow and blue outdoor jacket, a cream T-shirt with coloured hoops, beige coloured trousers, blue canvas shoes, and a blue cap. He has a bicycle which is described as a black Apollo mountain bike.

He was seen leaving Bordon Working Men’s Club, on Varna Road, between 10pm and 10.45pm on Thursday, August 6, on his bicycle.

The next sighting is just after 6am the next morning (August 7) when a member of public called police after seeing a man on the hard shoulder of the eastbound carriageway of the M27 at junction 12. He was heading west. Officers picked him up and he was taken to Havant railway station at around 6.20am.

At around 9.30am, he got off a train at Haslemere railway station and was later seen at the same location on CCTV at 11.25am. Officers attended the railway station just before noon and a short time later an ambulance was called.

The man was taken to Royal Surrey County Hospital and later transferred to St George’s Hospital where he remains in a critical condition.

Investigating officer Detective Sergeant Andy Greaves said: "At this stage we are appealing to any members of public who may have seen this man or come into contact with him to come forward.

"We have released a CCTV image in the hope that it will jog someone’s memory. He may have used several modes of transport, including his bicycle. Any details could help fill in the gaps of his movements and assist us in establishing how he sustained his injuries.

"I would urge anyone with any information to call 101. Your help could prove vital to the investigation.”

Anyone who can assist detectives with their investigation is asked to call Surrey Police on 101, quoting reference 45150069838, or by using the online reporting system at surrey.police.uk. Alternatively, call independent charity Crimestoppers anonymously on 0800 555111.
