Once they got into the building, the crowd threw out of windows the blankets and other objects the protesters inside
had been using. Police said no one was hurt.
The National Guard has now surrounded the building.
The protesters who had been occupying the Supreme Court were demanding the resignation of Supreme Court Chairman Kurmanbek Osmonov and other judges. The protesters were supporters of candidates who had either been disqualified or who had been defeated in parliamentary elections earlier this year. Their appeals had been rejected by Krygyz courts.
Unrest over the elections -- which were declared unfair by international monitors -- led to the eventual ouster of President Askar Akaev.
