A man is in critical condition after suffering an unexplained head injury earlier this week.

The 56-year-old was found lying unconscious on the floor in Oxford Road, Wincheap just before 1am on Wednesday.

Police, ambulance crews and the air ambulance were called to the scene.

He was flown to King's College Hospital in London with a serious head injury where he was admitted to the major trauma centre.

He is currently in a critical but stable condition and his family are with him at the hospital

The man had been to the Run of the Mill pub in Sturry Road on Tuesday night and had taken a taxi to Oxford Road where he had been dropped off almost an hour before he was found.

There is currently no evidence to suggest anything suspicious, but officers would like to hear from anyone who saw or heard anything.

Anyone with information is asked to contact DI Andy Bidmead on 101 quoting incident number 04-0035.
