Pirate Bay co-founder Peter Sunde was arrested in Southern Sweden on Saturday, Reuters reported. Sunde was convicted of aiding copyright infringement in 2009 and was sentenced to a year in prison, plus a fine. That year of jail time was reduced to eight months, but in 2012 Sunde failed to appear at the Swedish prison where he was to be incarcerated, and he has been wanted by Interpol ever since.

Sunde, who was arrested in the Swedish county of Skåne, had been living in Berlin when Ars caught up with him a month ago. He had recently launched a campaign to represent Finland as a member of the European Parliament, and he seemed fairly confident that he would not be taken into custody. As Ars reported in May:

”In a Skype text chat with Ars, Sunde said that his standing conviction in Sweden isn’t a barrier to his running for office, nor has it been a barrier for his ability to live and travel throughout Europe. “Well, I have multiple appeals in and few people looking for me,” he said. “As in, there's no need for me to be in Sweden, and basically no one wants me to go to prison. So no one looks for me outside of Sweden. “It's quite easy to cross borders in Europe without any controls. And the Nordic Union, don't forget—the Nordic countries has been passport-free since ages before Schengen,” Sunde added. He was referring to the Schengen Agreement, which has effectively eliminated internal passport control within Europe. Sunde said that he wasn’t sure if there was a warrant out for his arrest in Sweden. “No idea,” he said. “Probably? Well, besides not being a hard criminal, nor being in Sweden, I also have no €10 million ($13.8 million) to give anyone.”

It is unclear why Sunde was in Sweden at the time of his arrest, and Swedish officials have not provided further details.

Sunde and three other Pirate Bay principles who were also found guilty of violating copyright law had put in multiple appeals over the last several years to try to overturn the convictions, largely without success (one of the earlier convictions reduced the Pirate Bay co-founders' prison sentences, but increased the fines they'd have to pay). The Swedish Supreme Court declined to hear Sunde's appeal in February 2012, so the Pirate Bay leaders took their case to the European Court of Human Rights, which then dismissed their case unanimously as “inadmissable.”

One of the other Pirate Bay co-founders, Gottfrid “anakata” Svartholm Warg, was apprehended in Cambodia in late 2012 and remains in Swedish custody. In June 2013 he was also charged with hacking and fraud and sentenced to two years in prison, but he was later acquitted of fraud and had his sentence lowered to one year. Fredrik “tiamo” Neij, another co-founder, has not yet served time and appears to still live in Laos with his wife.

Correction: This article originally stated that Gottfrid Svartholm Warg was found guilty of hacking and fraud and was sentenced to two years in prison, but failed to note that he was later acquitted of fraud and had his sentence lowered to one year. Ars regrets the error.

Update Monday 8:40am CT: Ars received an e-mail from Benjamin O.J. Boman of the Swedish Prison and Probation Service, saying that Peter Sunde "is detained in a Swedish institution and will now serve his sentence. Information about a person what is or has been in detention or prison is confidential in Sweden, due to the provisions of the Swedish secrecy act, 35 kap. 15 § offentlighets- och sekretesslagen (2009:400)."
