OTTAWA (AFP) - A global manhunt was under way Friday for a Canadian porn star suspected of dismembering his boyfriend and mailing the body parts, after a video of the grisly killing surfaced online.

Interpol posted the picture and profile of Luka Rocco Magnotta, 29, who is being hunted across Canada over the killing, first brought to light when a human foot was sent to the headquarters of Canada's ruling Conservative Party.

A hand was later found in the mail at an Ottawa post office, and a torso was discovered in Montreal. Police believe the remains belong to a man who was dating Magnotta -- and that Magnotta is to blame.

Authorities say they believe the suspect, also known as Eric Clinton Newman and Vladimir Romanov, may have fled the country.

Interpol said it had issued a "Red Notice" wanted persons alert for Magnotta to its 190 member countries.

"There is no country in the world that is not talking about him," Montreal police commander Ian Lafreniere told public broadcaster CBC Thursday, adding that police have evidence he fled North America.

"There's a lot of heat on him. There's a lot of pressure on him, so we believe that it's going to be hard for him."

The video circulating online shows a man repeatedly stab another man with an ice pick and dismember him, as a song from the soundtrack of the film "American Psycho" plays in the background.

"It's a video of the murder," police told the daily Globe and Mail. The newspaper also reported that the footage showed acts of cannibalism.

Despite efforts to take it down, frustrated police said Thursday the gory 10 and a half minute video first brought to the attention of Canadian authorities by a Montana lawyer has kept popping up all over the Internet.

U.S. civil litigation lawyer Roger Renville told the Canadian Broadcasting Corporation (CBC) he came across the video last Saturday, and informed police in the United States and Canada.
"What I saw in that video exceeds your worst nightmare. It's Jeffrey Dahmer-esque," he said.

When Renville spoke to Canadian police on Sunday, he said they were "very skeptical."

A police officer "suggested that whatever I was seeing must be fake. And he suggested that special effects are pretty good these days and it'd be hard to tell if it was real or not," said Renville.
