A MURDER investigation is continuing following the death of a 26-year-old man in Oxford.

Alex Smith, of no fixed abode, was found with serious head injuries in the St Ebbe's area of the city, on Saturday December 15.

He died in the John Radcliffe Hospital, in Headington, on Monday.

The cause of his death is unknown. A post-mortem examination, held at the John Radcliffe Hospital, yesterday, proved inconclusive.

Detectives yesterday arrested a 38-year-old man, from Oxford, on suspicion of murder. He was questioned at St Aldate's Police Station for several hours, but released later.

He was granted police bail and was due to return to the police station today.

It is understood Mr Smith had used the facilities at Oxford Night Shelter, in Luther Court.
