"The court granted the petition of the investigation and chose Petriychuk a measure of restraint in the form of detention for a period until July 4," TASS quotes the decision of Judge Natalia Cheprasova.

Investigators previously sent a petition to the Zamoskvoretsky Court of Moscow for the arrest of theater director Evgenia Berkovich and playwright Svetlana Petriychuk in the case of justifying terrorism.

According to the director's mother, Elena Efros, the case was opened because of the play "Finist - Clear Falcon".

The play "Finist - Clear Falcon" was staged based on the play by Svetlana Petriychuk as part of the project "Daughters of Soso" in Moscow.

It tells the story of women who decided to virtually marry representatives of radical Islam and go to them in Syria.
