Russian police have arrested two more opposition activists in connection with the violence that broke out at an opposition demonstration in early May.
A spokesman for Russia's Investigative Committee, Vladimir Markin, said that Nikolai Kavkazsky and Aleksei Polikhovich were taken into custody and will face charges of participation in the unrest.
Markin said police searched the homes of the two activists and seized their computers and clothing the pair allegedly wore on the day of the protest on Bolotnaya Square.
Fourteen other activists are already facing charges for their alleged roles in the demonstration.
The May 6 protest -- on the eve of Vladimir Putin's inauguration for a third term as president -- included clashes between police and protesters.
More than 400 people were detained.
