MOSCOW, November 1 - RAPSI. The Moscow Basmanny District Court extended the house arrest of 18-year-old Muscovite Alexandra Dukhanina, who was arrested on charges related to the May 6 riots at Bolotnaya Square, a court spokesperson told the Russian Legal Information Agency (RAPSI/rapsinews.com).

The court has satisfied a motion by the investigator's office to extend her house arrest until March 6, 2013. Investigators believe Dukhanina cannot be subjected to any further restrictions.

Clashes with police flared up during an opposition march in Moscow on May 6. The public demonstration had been granted a city permit.

Dozens of protesters and police officers were injured as police detained over 400 protesters.

In June, investigators searched the homes of the rally organizers and participants, including those of Alexei Navalny, Sergei Udaltsov, Ilya Yashin, and Boris Nemtsov.

Among the individuals that were detained in connection with the investigation were Alexandra Dukhanina, Andrei Barabanov, Maxim Luzyanin, Yaroslav Belousov, Rikhard Sobolev, Vladimir Akimenkov, Oleg Arkhipenkov, Fyodor Bakhaov, Artem Savyolov, Alexander Kamensky, Mikhail Kosenko and Stepan Zimin.

Kamensky was later released. No charges were brought against him.

Maria Baronova, who was released, is also a suspect in the case.

Luzyanin, Barabanov, Zimin, Lutskevich, Dukhanina, Belousov, Savyolov, and Kosenko were charged with inciting the riots. Nearly 1,300 people were summoned to testify in the case.
