Unexplained East Haddon death being treated as murder
Police are looking into an incident at a Northampton pub they believe might be linked to their investigation
The unexplained death of a man in East Haddon is being treated as murder.
Northamptonshire Police says it received a report about the sudden death of a 43-year-old man shortly before 5:45am on Sunday.
A forensic post-mortem on Sunday failed to confirm a provisional cause of death, with a fast-track investigation being led by the East Midlands Special Operations Unit.
As part of this, detectives have been looking into an incident at Rosie O'Leary's pub in Fish Street, Northampton, on Saturday evening.
On Sunday morning, a 24-year-old man from the Daventry area was arrested on suspicion of murder.
He remains in custody on Monday.
Detective Chief Inspector Simon Barnes said the force's "fast-moving investigation is dedicated to answering all the necessary questions" into the man's death.
Anyone with information is being urged to call Northamptonshire Police on 101, quoting Operation Weymouth or incident number 24000699476.
