Two people have been arrested on suspicion of murder after the body of a man was found in a river in Ipswich.
The body of Joe Pooley, 22, was discovered in the River Gipping on Monday 13 August.
His death was initially being treated as unexplained, and a subsequent post-mortem examination revealed that it's likely he died from "immersion in water."
A 28 year-old-man and a 28 year-old woman, both from Ipswich, were arrested on Tuesday 2 October and are being questioned at Martlesham Police Investigation Centre.
A 36-year-old woman from Ipswich has also been arrested on suspicion of perverting the course of justice.
