BERLIN â€"  The Canadian porn actor suspected of murdering and dismembering a Chinese student in Canada before fleeing to Europe is to be brought before a judge in Berlin on Tuesday, a day after his arrest, as authorities kick off the process of seeking his extradition.

Luka Magnotta, 29, was arrested on Monday at an Internet cafe in a working-class district of the German capital, where he had been reading media coverage of himself. A cafe employee recognized Magnotta from a newspaper photo and flagged down a police car.

Magnotta was being held at a police detention facility in Berlin and was to be brought later Tuesday before a judge for a decision on a formal detention order, which would keep him in custody while proceedings continue. Such hearings must be held by the end of the day following a suspect's arrest in Germany, and always take place behind closed doors.

Once a detention order is issued, German authorities can contact their Canadian counterparts regarding extradition proceedings, police spokesman Klaus Schubert said.

Magnotta is wanted by Canadian authorities on suspicion of killing Jun Lin, a 33-year-old man he dated, and mailing his body parts to two of Canada's top political parties before fleeing to Europe.

They say Magnotta filmed the murder of the Chinese student in his Montreal studio apartment and posted it online. The video shows a man with an ice pick stabbing another naked, bound male. He also dismembers the corpse and performs sexual acts with it in what police called a horrifying video.

In Germany, surveillance camera footage of the Internet cafe, obtained by The Associated Press, showed Magnotta casually walking in to the shop at noon local time, wearing jeans, a green hoodie sweater and sunglasses.

He briefly spoke to the Internet cafe's desk person, then walked off to his assigned computer with the number 25 where he would later be spotted reading the news about his case.

About two hours later, seven German police officers are seen walking into the shop, without any haste.

On the camera footage, three police officers are seen accompanying the handcuffed Magnotta a couple of minutes after they first entered the cafe. Magnotta calmly walks alongside them.

Police say he at first tried giving fake names but then conceded: "You got me."
