INVESTIGATORS were seen combing a house for clues as enquiries into an alleged murder continued.

The inspection of the property in Elgin Street, Halliwell, came after a 49-year-old man, named locally as David Molloy, died on Sunday.

He had been arrested after a fight at the address in the early hours of the morning and became ill in the back of a police van as it travelled along St Peter's Way.

Despite attempts to revive him at the side of the road, he later died in hospital.

Officers said in a statement the man suffered a medical episode in the police vehicle.

They later returned to the house in Elgin Street and arrested a 34-year-old man, who was released under investigation on Monday.

Two crime scene investigation vans were at the address yesterday, as inspectors in white searched the house.

A police car has been stationed outside for the last few days since the incident.

When police responded to reports of the disturbance at a house, which is believed to be a rented property, officers spoke to the two men who had been involved in an altercation and the 49-year-old man was arrested on suspicion of breaching the peace.

In line with standard policy, the Independent Police Complaints Commission has been informed and is investigating the circumstances surrounding the incident.

A spokesperson for the IPCC said: "Following a referral from Greater Manchester Police we have begun an independent investigation into the circumstances surrounding the death of a man in Bolton in the early hours on Sunday morning."

Anybody with information is asked to contact police on 101, quoting incident number 255 of September 10.
