POLICE say that four men who were arrested following the death of a man in the West Hill area of Bournemouth in October have been released but remain under investigation.

The men were detained after officers were called to reports of the sudden death of a man in his 50s at a property in St Michael's Road, just before 9.40pm on Monday, October 21.

At the time police said the death was 'suspected drug-related' and an initial post-mortem took place on Thursday, October 24.

A spokesman for Dorset Police said: "The four men who were arrested remain released under investigation and our enquiries are continuing. We are not able to give any more information about the substance involved at this stage, other than to reiterate as we have already stated that we are treating this as a drug-related death."

The four Bournemouth men, who were aged 20, 25, 35 and 40, were arrested on suspicion of administering poison with intent to endanger life or inflict grievous bodily harm.

The men aged 20 and 25 were also arrested on suspicion of supplying a controlled drug of class A, B and C.
