Two teenagers have been arrested on suspicion of murder after a man was found dead in Oxford.
A 17-year-old boy, from Oxford, was arrested on Tuesday on suspicion of murder while a 16-year-old girl, also from Oxford, was arrested on suspicion of murder and grievous bodily harm with intent, Thames Valley Police said.
The pair remain in police custody.
It comes after the body of a 50-year-old man was found by officers at a property in Brome Place, Barton, on Sunday.
The force said he may have been assaulted the previous evening, but this was not reported.
