Police found what appears to be a human head in a park in Montreal and are investigating whether it is the missing head of a Chinese student who they say was dismembered by a Canadian porn actor, an official said Sunday. 
 
 A police official said it appears to be a human head. The official spoke on condition of anonymity because they were not authorized to speak about the details. 
 
 Luka Magnotta is accused of dismembering his lover Jun Lin and mailing the body parts to political parties and schools. He pleaded not guilty last month. Lin's head is the only remaining body part unaccounted for. 
 
 Montreal police spokesperson Anie Lemieux said investigators made their way to Park Angrignon on Sunday afternoon after the major crimes unit received a tip. The park is located a few miles (kilometers) south of Magnotta's apartment. 
 
 Lemieux said they must wait for tests results over the next few days to confirm if there is any link and whether it is in fact a body part. 
 
 Police have been questioning Magnotta with the hope that they would find out the location of the head. The family of Lin has been seeking closure. 
 
 Investigators say Magnotta, 29, posted a video online showing him having sex with the dismembered corpse. A second, unedited version of the video seen by police shows him eating parts of the body. Police say Magnotta and Lin were in a relationship. 
 
 The case became known when a package containing a severed foot was found at Canada's ruling Conservative Party headquarters on May 29. That same day, a hand was discovered at a postal facility, addressed to the Liberal Party of Canada. 
 
 Lin's torso was found in a suitcase at a garbage dump in Montreal outside Magnotta's apartment building. 
 
 About a week later, a missing foot and hand were found mailed to two schools in Vancouver. Police said notes were included in most of the packages but declined to say what they said. 
 
 Magnotta, who fled to Europe before the body was discovered, spent a few days partying in Paris before moving on to Berlin, where he was caught last month as he read stories about himself at an Internet cafe. He did not contest his extradition from Germany and arrived in Montreal last month on a Canadian military plane. 
 
 Lin's family arrived in Montreal last month and attended a memorial service last week. Lin, 33, studied computer science student at Montreal's Concordia University.

 Associated Press Writer Phil Couvrette in Ottawa, Ontario contributed to this report. ||||| Investigators in Berlin have detained a man whom they believe to be Luka Rocco Magnotta, a porn actor wanted in Canada for killing and dismembering someone and mailing body parts to political parties, a spokesman for the police in Berlin, Guido Busch, said Monday. 
 
 Authorities detained him after someone in an internet cafe told them she thought she recognized a customer in the cafe as the suspect, Busch said. The suspect offered no resistance when police took him into custody. 
 
 Magnotta is wanted on charges of first-degree murder in connection with the killing of 33-year-old Jun Lin, a Concordia University student from China, and threatening, among others, Canada's prime minister after mailing him a severed foot. 
 
 The case began last week when a package addressed to Prime Minister Stephen Harper arrived at his majority Conservative Party headquarters, and a hand was later found at a post office addressed to the minority Liberal Party, authorities said. 
 
 Authorities quickly traced the address on the packages to the Montreal apartment of Magnotta, where they discovered a torso in a suitcase in a trash bin. 
 
 And the crime, Montreal police say, was captured on a graphic video posted to the Web. It features a man - who authorities believe is Magnotta - killing another man, dismembering the corpse and performing sexual acts. 
 
 "We believe he filmed himself," LaFreniere said last week. "It's gross. ... This is a very deranged person. He is looking for attention, and he got it, but not in a positive way." 
 
 Not all the body parts have been recovered, and LaFreniere said forensic evidence and DNA were used to identify the victim as Jun. 
 
 Authorities believe Magnotta killed Jun on May 24 or May 25, posted the video, and on May 26 fled the country by plane to Europe. 
 
 That prompted Interpol, the global police agency, to alert authorities in 190 countries.
– The head of Luka Rocco Magnotta's former lover may finally have been recovered. Following a tip, police discovered an apparent human head in a Montreal park near Magnotta's apartment yesterday, the AP reports. Testing will help determine whether the head belonged to Jun Lin, a Chinese student allegedly killed and dismembered by Canadian porn actor Magnotta, and whether it's actually even a body part, a police rep said, according to the Toronto Star. Lin's head is the only remaining body part unaccounted for. Magnotta was extradited from Germany to Canada earlier this month.
