Meanwhile, the government faced allegations that police had acted under pressure from U.S. authorities when they targeted the file-sharing site in raids earlier this week.
The police Web site was closed late Thursday after a so-called denial of service attack, in which hackers overload a single network by directing massive traffic to the site.
In Wednesday’s crackdown on illegal file-sharing, police said they raided about 10 locations in central Sweden and detained three men linked to The Pirate Bay on suspicions of violating copyright laws.
The three Swedes were later released but could still face charges,
The raids were applauded by the Motion Picture Association of America, which claims movie studios lost US$6.1 billion to piracy last year.
An opposition lawmaker called on Parliament’s Constitution Committee to investigate the case after a report on public broadcaster SVT suggested the Justice Ministry ordered the raids on a U.S. request.
Under Sweden’s Constitution, ministers are not allowed to direct the work of the police.
