A MURDER investigation was under way today after a 21-year-old died following a mystery incident.

Gareth Bolwell, of Newbridge, was taken to the Royal Gwent Hospital, Newport, but was pronounced dead on Friday evening.

Officers are understood to be investigating Mr Bolwell's movements three days earlier.

But they are refusing to release further details.

A local man was arrested and was quizzed over the weekend but was released last night without charge.

Inspector Simon Jefferies, of Gwent Police, said: "The investigation is ongoing and centres around events on Tuesday, May 18, when Gareth was out in the Pantside area of Newbridge."

He said a post mortem examination had been carried out and that they were still awaiting the results to find out how Mr Bolwell died.

Anyone who had contact with Mr Bolwell or anyone having information is asked to contact Gwent Police on 01495 223673.
