A man is in custody after a body was found in a block of flats in the early hours of Christmas morning.
Bedfordshire Police said the death of the man, found in flats in Calshot Walk, Bedford, at 1.55am, is being treated as suspicious.
A spokeswoman said although the results of a post-mortem examination will not be known until Sunday, police believe he may have been assaulted.
Detective Chief Inspector Steve Collin urged anyone who may have seen or heard anything suspicious around the flats on Christmas Eve to get in touch.
He said: “A man has been arrested and remains in police custody.
“We are still in the early stages of the investigation and I would ask for anyone who was in or around the flats between 6pm yesterday and the early hours of this morning and saw or heard anything which could be related to this incident to contact the police.”
