Luka Rocco Magnotta, the Canadian porn actor suspected of murdering a man and mailing body parts to political parties, has been arrested in Berlin, police say. He was earlier believed to be in Paris. Magnotta, 29, is suspected of filming himself as he dismembered his boyfriend and mailing the body parts. The suspect has been dubbed Canadian Psycho by the press because a video circulating online and believed to be linked to him shows a man stab another man with an ice pick and dismember him while a song from the film “American Psycho” plays in the background. Interpol on Thursday issued a Red Notice wanted-persons alert for Magnotta, also known as Eric Clinton Newman and Vladimir Romanov, to its 190 member countries after a video of the grisly killing surfaced online. The killing came to light when Canadian police said Tuesday that a human foot had been 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. Canadian police believe the remains belong to a man who was dating Magnotta -- and that Magnotta is to blame. The victim, a student identified as Lin Jun, had been “in a relationship” with the porn star, according to Montreal police commander Ian Lafreniere.
