The death of a man found with head injuries is still being treated as unexplained four months after he was discovered in the grounds of Diss church.

The man, said to be in his 40s, was found by workers cutting the grass in St Mary's Church graveyard in the centre of the town at shortly before 9am on April 30.

The church and streets surrounding it remained taped off and a police cordon in place for almost 48 hours, whilst scene of crime officers began an investigation into the circumstances surrounding the death.

A Norfolk Police spokesman said the investigating remains on-going into how the man came to die with officers still waiting the outcome of toxicology tests.

The results of an initial Home Office post mortem examination proved inconclusive. But whilst the death remains unexplained, police do not believe there was any third party involvement.
