The 27-year-old Svartholm, who had been residing for several years in Cambodia's capital Phnom Penh, has been arrested at the request of Swedish authorities for a "crime related to information technology."
As a reminder: Svartholm, along with his Pirate Bay co-founders Peter Sunde and Fredrik Neij and Carl Lundström, CEO of The Pirate Bay's former ISP, had been sentenced in 2009 to one-year prison sentences and ordered to pay around $1 million each in restitution for copyright infringement to movie and music companies.
Sunde, Neij and Lundström successfully appealed to the court and got their prison sentenced reduced. Svartholm, who wasn't present at the appeal due to health problems, got stuck with the original sentence.
He was supposed to return to Sweden in January in order to begin serving the prison sentence, but he failed to show up, so the Swedish authorities issued an international warrant for his arrest.
According to TorrentFreak, Svartholm was arrested in his apartment and, despite the fact that Sweden and Cambodia don't have an extradition treaty in place, it is believed that the Cambodian authorities will soon find a legal way to deliver him to his native country.
