THE killer of a teenager whose dismembered body parts were found 60 miles apart was today staging a prison protest in a bid to be moved from his cell.

William Beggs -- once jailed for the murder of a Bolton man -- is understood to be refusing prison food at Saughton jail, Edinburgh, where he was sent last month for the murder of 18-year-old Barry Wallace.

Beggs, aged 38, of Kilmarnock, Ayrshire, reportedly wants to be transferred to an area of the prison inhabited by "drug-free" inmates.

He was jailed for life six weeks ago after being found guilty of sexually assaulting and murdering Mr Wallace in December 1999, then cutting up the teenager's body and disposing of the severed parts in two separate locations.

Trial judge Lord Osborne said Beggs, originally Moira in Northern Ireland, should serve a minimum of 20 years behind bars.

A spokeswoman for the Scottish Prison Service said: "We are unable to comment on the circumstances of individual prisoners."

In 1987, Beggs was convicted of the murder of Bolton-born Barry Oldham. He was jailed for life but an appeal court quashed the conviction two years later.
