The hunt for a Canadian porn star suspected of cutting off and mailing his lover's limbs continued Sunday with police carrying out  "targeted searches" in parts of Paris. Luka Rocco Magnotta remains at large after the gruesome killing of Chinese student Lin Jun, but an arrest warrant issued Thursday and obtained by CBC News, alleges he caused Prime Minister Stephen Harper and members of parliament "to reasonably fear for their safety or the safety of anyone known to them." "The accusation likely stems from police's belief that after cutting off the limbs of his victim, Magnotta mailed a foot to Conservative Party headquarters and a hand to the Liberals," said the report published late Friday on the broadcaster's website. In addition to the harassment count, Magnotta is suspected of "committing an indignity to a dead body," "publishing an obscene thing" and "mailing obscene matter," CBC added. Magnotta, 29, is the target of a global manhunt amid reports that he may be in France. 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. In France on Saturday, a police source said "targeted searches" were under way after an airport official stated that the passenger lists of flights from Canada were being checked. The source would not say if these searches were based on the known haunts of Magnotta on previous visits to France, or definite reports he was in the country. Investigators focused on a main road in the Batignolle neighbourhood of the capital's 17th arrondissement in the northwest of the city, the police source told AFP. Unconfirmed reports on TV news channel LCI late Saturday said the fugitive "met a witness judged to be credible in Paris on May 28" and police carried out another check in Seine-Saint-Denis to the north of the capital. Canadian investigators said Magnotta had flown from Montreal to France on May 26. But French police said on Friday they had "no certainty as to his presence in France." The suspect, who grew up in the Toronto suburb of Scarborough, has been dubbed "Canadian Psycho" because a video circulating online and believed to be linked to him shows a man stabbing another man with an ice pick and dismembering him while music from the film "American Psycho" plays in the background. The 32-year-old victim, who hailed from the city of Wuhan in central China, was studying at Montreal's Concordia University after arriving in the French-speaking province of Quebec in July. He was last seen on May 24 and was reported missing five days later.
