A porn actor accused of killing and dismembering a Chinese student in Canada has been extradited from Germany and is expected to be quizzed by police about his victim's missing head.
The international manhunt for Luka Rocco Magnotta ended earlier this month when he was detained by officers in a Berlin internet cafe, while looking up online articles about himself.
The 29-year-old did not fight extradition to his native Canada, where he is suspected of slaying Jun Lin and sending body parts to Canadian political parties and schools.
Mr Jun, 33, was a former lover of Magnotta, who has been dubbed the "Canadian Psycho" and fled Canada on May 26, initially to Paris before boarding a bus to Berlin.
Investigators say he filmed himself on the night of May 24 using a pickaxe to kill his victim, who was studying computer science in Montreal.
The torso was found in a suitcase at a rubbish dump in Montreal outside Magnotta's apartment building.
Canadian justice minister Rob Nicholson said in a statement that Magnotta was removed from Berlin on Monday by a Canadian military plane.
Montreal police commander Ian Lafreniere said after the plane landed: "This is not the end of the investigation.
"We're missing an important part of the investigation which is the head of the body."
Yan Shi of the Concordia Chinese Students Association said the victim's family remains in Montreal, after travelling to Canada from China following the death.
