Severed head linked to 'cannibal' porn actor Luka Magnotta

Police have found what appears to be a human head in a park in Montreal and are investigating whether it is the last missing remains of a Chinese student they believe was dismembered by a Canadian porn actor.

Luka Magnotta is accused of mailing parts of the body of his lover, Jun Lin, to political parties and schools, with Mr Lin's head the only piece still unaccounted for.

Last month Mr Magnotta pleaded not guilty to murdering Mr Lin, a Chinese student who was attending university in Canada.

Investigators made their way to Angrignon Park, a few miles south of Mr Magnotta's apartment, on Sunday afternoon after receiving a tip.

But they must wait a few days for test results over the next few days to confirm if there is any link – or, indeed, whether it is in fact even a body part, such is its condition.

Police have been questioning Mr Magnotta with the hope that they would find out where the head was.

Investigators claim Mr Magnotta, 29, posted a video online showing him having sex with the dismembered corpse.

A second, unedited version of the video seen by police allegedly shows him eating parts of the body.
