Mikhail Schneider, a leader of Russia's opposition Solidarity movement, intends to file a claim to the European Court of Human Rights over his detention on charges of attempting to stage an unsanctioned march.
Schneider, along with another Solidarity leader, Boris Nemtsov, and prominent human rights activist Lev Ponomarev, were detained in downtown Moscow on Sunday, during celebrations dedicated to National Flag Day.
The three detainees spent more than 12 hours in custody before being released.
On Thursday, a Moscow court ruled to jail Schneider for three days on charges of participating in an event that "bore the hallmarks of a march."
Schneider, who rejects all the charges, was released late on Saturday.
"The law enforcement officials who detained me should be brought to trial. Judges should also bear responsibility," he said.
Following Schneider's arrest, his lawyer filed an appeal against the court's decision, which was rejected on Friday.
