A Canadian man who is suspected of killing and filming the dismemberment of his boyfriend, has been arrested in Berlin.

Mass-circulation daily Bild said Luka Rocco Magnotta was picked up by authorities in an internet cafe in Neukoelln, a working-class district of Berlin.

A spokesman for the Berlin police confirmed that a man had been arrested on the basis of an international arrest warrant but declined to confirm the suspect's identity.

French police had earlier said they were checking whether Mr Magnotta, a 29-year-old former porn star, may have fled Paris for other parts of France or Europe through an international bus station.

One employee at the station claimed to have seen Mr Magnotta board a bus to Berlin on Friday night, while another said someone bearing a close resemblance to the suspect had boarded a bus for Romania.

Mr Magnotta has been dubbed the 'Canadian Psycho' by the press because a video circulating online and believed to be linked to him shows one man stab another with an ice pick and dismember him while a song from the film 'American Psycho' plays in the background.

Interpol on Thursday issued a Red Notice wanted-persons alert for Mr Magnotta, also known as Eric Clinton Newman and Vladimir Romanov, to its 190 member countries after a video of the grisly killing surfaced online.

The murder came to light when Canadian police said that a human foot had been sent to the headquarters of Canada's ruling Conservative Party.

The victim, a student identified as Lin Jun, had been "in a relationship" with the porn star, according to Montreal police.
