Thylmann. (Chris Morris for CNBC.com.)

Fabian Thylmann, the managing partner of the company that operates erotic websites such as YouPorn and PornHub, was arrested in Begium, according to the website of the German newspaper Die Welt.

Mr. Thylmann, who serves as managing partner of Manwin, was reportedly arrested in the Brussels airport on suspicion of tax evasion. The warrant for his arrest was signed in Cologne, Germany.

While Manwin bills itself as an information technology firm, the Luxembourg-based company is best known for running pornography websites, and overseeing Playboy's web and TV operations.

There's nothing in the Die Welt article indicating whether any of Manwin's sites will be affected.

Betabeat has reached out to a spokeswoman for Mr. Thylmann, and will update when we receive comment.

In the meantime, we leave you with a list of some of the other websites operated by Manwin (per XBiz.com):

Digital Playground, Brazzers and Twistys. In addition, Manwinowns Reality Kings, YouPorn, Spankwire, Webcams Tube8, ExtremeTube, KeezMovies, Mofos, ExtremeTube, JuicyBoys and PornHub.

May your service be unaffected.
