Pirate Bay co-founder Gottfrid Svartholm Warg, who disappeared while facing a jail sentence and hefty fine in Sweden for aiding in copyright infringement, has been arrested in Cambodia, according to a report.

Warg was arrested on Thursday by Cambodian police in Phnom Penh, reports TorrentFreak, which points in its story to a piece in Swedish-language newspaper Svenska Dagbladet.

The reason for the arrest has not been officially announced by Swedish or Cambodian authorities, TorrentFreak reported. Borrowing from the SvD report, it quotes Warg's lawyer, Ola Salomonsson, as saying, "As far as I understand it is because he is on an international wanted list." (See update below as well.) Salomonsson also said Warg could be sent back to Sweden eventually, though there's no extradition treaty between that country and Cambodia.

Warg -- along with his Pirate Bay cohorts Peter Sunde, Fredrik Neij, and Carl Lundström -- was found guilty in 2009 of having made 33 copyright-protected files accessible for illegal file sharing via the Piratebay.org Web site. The four men were each sentenced to a year in jail and were also ordered to collectively pay a total of 30 million Swedish kronor ($3.6 million) in damages to copyright holders, among them a number of American media giants.

An appeal attempt by Sunde, Neij, and Lundström came to an end this past February when the Sweden Supreme Court refused to hear their case.

Warg failed to appear at the initial appeal hearing in 2010, presenting a medical certificate that said he was confined to a hospital in Cambodia, TorrentFreak notes. But he also failed to show at a subsequent hearing and has been missing ever since. In the meantime, his sentence and $1.1 million share of the fine were finalized in Sweden's courts.

Warg was due to begin serving his jail sentence in January.

Update, 10:38 a.m. PT: Swedish newspaper Aftonbladet reported that a Swedish Foreign Ministry representative confirmed only that a Swedish citizen had been arrested in Phnom Penh and said (according to Google Translate), "There is a man in his 30s who was arrested because he was on an international wanted list."

Correction, September 4 at 10:33 a.m. PT: The proper name of the subject of this story is Gottfrid Svartholm Warg. The story originally dropped his last name.
