Montreal - A porn actor accused of slaying and dismembering a Chinese student in Montreal last month will appear in court in Montreal on Tuesday, police spokesperson Ian Lafreniere said.
Police believe 29-year-old Luka Rocco Magnotta, dubbed the "Canadian psycho", used an ice pick to stab Lin Jun - a Chinese student at Montreal's Concordia University - sometime between 24-25 May.
The suspect is thought to have then carved up the victim's body and filmed the act. A video that police believe shows the killing, dismemberment of the body and sexual interference with the corpse, was posted on the internet.
Magnotta was extradited from Germany (where he had fled) to Canada on Monday in a case that has sent shock waves across the globe.
He landed back in the country aboard a military jet in the custody of Montreal police and officers from the Royal Canadian Mounted Police, officials said.
"Our government's co-operation with the international community has led to this individual being swiftly returned to face justice," Canadian Attorney General Rob Nicholson said.
"It is important that Canadians can have confidence that those who are accused of serious crimes will face the full force of the law," he added.
The aircraft arrived in Montreal after a flight from Berlin, but Canadian police did not immediately say where Magnotta would be held.
Police in Montreal were galvanised on 29 May when Lin's torso was discovered in a suitcase by the trash outside an apartment along a busy highway.
The victim's hand and a foot were sent, meanwhile, to federal Conservative and Liberal parties in Ottawa through Canada Post. And a severed foot and hand that belonged to Lin were delivered to two schools in Vancouver. Lin's head is still missing.
Magnotta initially fled Montreal for Paris in the aftermath of the killing, prompting Interpol to issue an international alert. He was arrested in a cyber cafe in Berlin on 4 June, after being spotted reading about himself on the internet.
Officials here say Toronto-born Magnotta will face charges of first degree murder, committing indignities to a body, publishing and mailing obscene material and criminally harassing Canadian Prime Minister Stephen Harper and other members of parliament.
An escort and occasional actor in the porn industry, Magnotta had been estranged from his Ontario family for years. An anonymous relative who had known Magnotta since childhood told the Peterborough Examiner, an Ontario newspaper, that Magnotta was "a ticking time bomb".
"He's a nut job. I did not trust him. I think he's mentally ill. He has delusions of grandeur. He concocts stories that he tends to believe and they in turn become fact in his mind," the relative said.
Magnotta, who used several aliases and whose birth name was Eric Clinton Newman, is believed to have once had a sexual relationship with Lin.
Lin's parents, who arrived in Montreal earlier this month to meet with investigators and officials, had called for Magnotta's quick extradition. The family said they were devastated by their only son's murder, saying he had been their "pride and hope".
Family and friends described Lin, who excelled in engineering and computer science at Concordia, as kind, compassionate and responsible.
