Canadian Luka Rocco Magnotta, suspected of murdering and dismembering a Chinese student in Montreal, is due to appear in court in Berlin later today.
Mr Magnotta (29) was arrested in an internet cafe in an internet cafe in the Neukoelln district in the German capital yesterday afternoon.
Interpol issued an arrest warrant last week for Mr Magnotta, who faces first degree murder charges over the videotaped death of the student, whose body parts were mailed to political parties in the Canadian capital Ottawa.
He is believed to have entered France on May 26th, and French police had been investigating thousands of reported sightings. They alerted German police yesterday that he was headed for Berlin on a Eurolines coach.
Mr Magnotta was found in a cafe on Karl Marx Strasse, a busy shopping street running through the multi-cultural south-Berlin district, which is home to numerous Turkish and Lebanese cafes and snack bars.
German television quoted the owner of the cafe as saying that Mr Magnotta had spent an hour surfing the internet before police entered and took him into custody.
The 29-year-old has left a bizarre Internet trail as an alleged kitten-killer and bisexual porn star.
In a crime scene Montreal police say is the worst they have seen, his apartment included a bloody mattress and pools of blood on the floor and in the refrigerator. The police said a janitor found a torso with no head or limbs in a suitcase in an alley behind the building.
Authorities believe that a decomposing foot mailed to the headquarters of the governing Conservative Party in Ottawa on Tuesday last and a hand found inside a package at a postal depot are parts of the same person.
Mr Magnotta, faces first degree murder charges in the death of 32-year-old Jun Lin. Mr Magnotta, who used at least three identities and was an avid internet user, is believed to have killed Lin with an pick axe, dismembered and defiled his body and then mailed some of the body parts out.
"There was great relief among investigators when we heard this news," Montreal police spokesman Ian Lafreiniere told reporters in the Canadian city where the murder took place.
"He used the web to glorify himself, and it was the web that got him arrested."
The horrific, gruesome murder prompted the largest manhunt in Montreal's history, Mr Lafreiniere said.
Canadian police have not ruled out the possibility that Mr Magnotta was involved in other crimes.
The owner of the Berlin Internet cafe in which Mr Magnotta was found, Kadir Anlayisli, told Reuters Television: "I wasn't sure if it was him but then I looked at some pictures and thought, that is definitely him. He spoke French, said 'monsieur' and wanted to use the Internet."
Mr Anlayisli said he stepped out of the cafe, stopped a passing police van and told them, "I have someone here you might be looking for."
The suspect is being held at a Berlin police station. Interpol red notices require that the suspect be held under arrest pending extradition.
It is unclear when Mr Magnotta might be returned to Canada.
Canadian prime minister Stephen Harper said he wanted to congratulate German and French police for their good work in apprehending the suspect.
