The new orders are reportedly linked to threats coming against the families of police officers who had been involved in a crackdown on a peaceful protest in Moscow July 27, and whose names and hyperlinks to their social media accounts were shared online.

"Captain Syakin's family was the first to file a complaint. Data published online allowed certain activists finding his relatives and slipping a note under the door at the home of Syakin's mother that read, 'We'll burn down your home'," Baza reports.

On July 27 in Moscow, police officers and National Guardsmen used force to disperse several thousand demonstrators, leading to several activists being hospitalized.

Ukraine has condemned the violent crackdown on a peaceful rally, noting violations of human rights.

Meanwhile, Moscow's Investigative Committee has opened three criminal cases against protesters for allegedly "attacking" police officers.

As UNIAN reported earlier citing a Washington Post editorial, the latest Moscow protests suggest that despite the authoritarian rule of President Vladimir Putin over nearly two decades, there is still a significant number of people in Russia's capital not afraid to speak out. It also suggests that "Mr. Putin knows of this discontent and fears it."
