Berlin, Germany - A Berlin court remanded a man into custody Saturday on suspicion of firebombing mosques in the German capital over the past several months.
No one has been injured yet, but German Muslims have been increasingly worried by the attacks.
The suspect, 30, was picked up Friday night by detectives who traced him through a newspaper clipping he had ordered from a city newspaper, B.Z.
The photocopied clipping was left at the scene of one attack as a claim.
Police said he had admitted some attacks, without specifying if he had claimed to be behind all of them. His name was withheld under German privacy and defamation laws.
Berlin's biggest mosque, the Turkish Sunni community's Sehitlik Mosque, was firebombed four times in recent months.
The Ahmadiyya community's mosque was also attacked, as was a building in Tempelhof district, the Islamic Cultural Centre.
The petrol bombs scorched the facades, but did no other damage.
Political parties and Germany's Jewish communities were among those who had urged police to make the attacks a priority.
Police with a warrant searched the offices of B.Z. on Friday after forensic experts had decoded a photocopier watermark on the clipping and decided it had come from a news company photocopy machine.
