Fabian Thylmann, 34, was apprehended last week after a German court in the western city of Cologne issued a warrant, a court spokesman said late on Monday.
“Mr. Thylmann is currently in custody in Belgium awaiting extradition,” the spokesman told the daily newspaper Die Welt.
Thylmann also manages several other sites such as Pornhub, Brazzers and the German amateur pornography portal MyDirtyHobby. On Tuesday, police searched his home and offices and seized documents and computers.
Though his companies are registered in Luxembourg, Germany, Canada, Cyprus, the Untied States and Ireland, the porn mogul lives in a suburb of the Belgian capital Brussels.
Originally from Aachen in western Germany, Thylmann built up a pornography empire in just a few years through the holding company Manwin Holding SARL, according to Die Welt.
The paper recently reported on what it said were financial irregularities at the Manwin group, prompting Thylmann to take legal action to get the paper to cease and desist writing. Die Welt said it had contested the action and that a court ruling was expected before the end of the year.
