A woman murdered in a South Wales village in what unconfirmed reports described as a cannibalistic attack has been named by police.

Sources say Cerys Marie Yemm (22) was pronounced dead at a bed and breakfast in Argoed, in the Valleys, after being found with substantial facial injuries.

Police fired a 50,000-volt Taser at Matthew Williams in an effort to stop his attack, before the 34-year-old man was restrained and arrested. He later died in custody.

Gwent Police said they were not looking for any other suspects in the murder investigation. Officers have refused to comment on her injuries or reports they were in a relationship.

The attack happened at around 1:30am on Thursday at the Sirhowy Arms Hotel, used by Caerphilly Council to house homeless people while they wait for permanent accommodation.

Neighbour Susan Gibbs said: "We have had a lot of problems up there. Every other week, well every other day sometimes, there are police up there."

Leon Gardiner, deputy mayor of the village, 20 miles north of Cardiff, said: "This has hit the community for six."

He said: "This is the sort of thing you don't ever expect...We've just got to live with it and hope that the hurt goes away - but it will take a long time."

The Independent Police Complaints Commission has started its own probe into the suspect's death.

A Gwent Police statement confirmed "a Taser was discharged and a 34-year-old local man was arrested. Whilst under arrest, the man became unresponsive. Officers and paramedics administered first aid but he was also pronounced dead at the scene."
