Two men have been arrested on suspicion of murder after a woman was found dead at a flat in Bury St Edmunds.

Police were called at 10.20am yesterday to a block of flats in Anselm Avenue by the ambulance service.

A 49-year-old man was arrested yesterday morning, with a 22-year-old man arrested on Sunday evening. It is understood at least one of the men, the 49-year-old, knew the victim who is in her 30s and lived at the flat.

Detectives have not said at this stage how the woman died.

Neighbours reported hearing fireworks being let off behind the block of flats at around 10pm on Saturday and said that an ambulance also visited the block around the same time.

The property was cordoned off from 10.30am yesterday, while police tape was also placed on fencing at the rear of the flat. Police officers were positioned at the front door and at a rear entrance in the garden of one of the flats.

The incident took place at an old townhouse that has been converted into six large apartments.

One neighbour, who lives next to the flats and did not want to be named, said: “It’s very sad.”

A Home Office post mortem examination will be carried out to ascertain cause of death,
