Three senior politicians from Greece's far-right Golden Dawn party have been released pending their trial on charges of belonging to a criminal group.
Court officials told the Associated Press a fourth politician, Ioannis Lagos, was jailed ahead of the trial.
The Golden Dawn party members were arrested at the weekend following an investigation into the fatal stabbing of 34-year-old Greek hip-hop artist and anti-racism campaigner Pavlos Fyssas.
All four denied charges against them in a marathon plea session before an investigating magistrate that ended early this morning after more than 18 hours.
