MOSCOW, July 27. /TASS/. Police officers have detained almost 300 participants of an unauthorized rally in central Moscow, the press service of the Moscow Main Directorate of the Interior Ministry told TASS.

"Two hundred and ninety-five people have been detained at an unauthorized rally in the center of the capital for the breach of peace," a police officer said.

He added that a considerable number of detained people are not Moscow residents. "All the detained people are being taken to local police departments for investigation," the source added.

The authorities earlier warned the participants of the unauthorized rally on July 27 of responsibility and the inadmissibility of law violations. Moscow Mayor Sergei Sobyanin said that, according to law enforcement authorities, provocations are being prepared that pose a threat to people’s life, health and security. The Moscow Main Directorate of the Interior Ministry also called for restraining from participation in the rally and promised to take all the necessary measures to provide people’s security and prevent and suppress any violations of public order.

Moscow prosecutors are conducting an administrative investigation into 15 unregistered candidates to the Moscow City Duma who are organizers of the unauthorized rallies of July 14 and 27. They ignored the first warning of the prosecutors. Then the prosecutors made a second warning of the inadmissibility of law violations and responsibility in case of a breach. The lawyers interviewed by TASS also called for abandoning "revolutionary games" and turning hand to useful work, or coming to the unauthorized rally with a lawyer, as participation in it entails administrative responsibility in the form of a fine and arrest, but a criminal case may also be launched.
