Canadian police are searching for a porn actor wanted in connection with two packages of human limbs in Ottawa and a headless torso in Montreal, BBC News reported.

Luka Rocco Magnotta, 29, has been named as a suspect by the Montreal police, who have taken over the case.

A blood-soaked package containing a human foot was delivered to the offices of Prime Minister Stephen Harper's Conservative Party on Tuesday, May 29.

The second package, containing a hand, was found by police on Tuesday night.

That parcel was addressed to the Ottawa office of the Liberal Party, Canadian media reports. Montreal police told the BBC that they believed the torso and the limbs were from the same body, but were waiting for test results to confirm this.

Mr Magnotta, who was also known as Eric Clinton Newman and Vladimir Romanov, worked as a bisexual porn actor and model, an official close to the investigation said.

Police described him as a white male, about 5ft 8in (1.78m) tall with blue eyes and black hair.

In a statement, Montreal police said their investigation had led them to an apartment close to where the torso was found in a pile of rubbish.

The apartment was searched while a forensics team was asked to analyse "elements of the scene", according to a police statement.

Montreal police told the BBC that the apartment belonged to Mr Magnotta.

Blood stains were found all over the apartment, police said. "For most of the officers that were there all night long this is the kind of crime scene they've never seen in their career," Police Commander Ian Lafreniere told the Associated Press news agency.
