A man whose death in Peterborough is being treated as murder has been identified by police.

The body of Michael Green, 23, of Muskham, Bretton, Peterborough, was found in an underpass near Tyesdale, Bretton, shortly after 1.20am yesterday.

Three boys, aged 15, 16 and 17, and a 16-year-old girl have been arrested on suspicion of murder and are in custody at Thorpe Wood Police Station.

Mr Green’s body was discovered by a dog walker and within a short time forensics officers were at the scene and a police cordon thrown round a local bus stop.

Initially police described the death as unexplained but only later, once the results of a post mortem were known, did it get treated as a murder investigation.
