The Investigative Committee opened criminal proceedings following the July 27 opposition protest and placed 14 suspects of what it called mass civil unrest in pre-trial detention. Charges of mass civil unrest carry a maximum prison sentence of eight years.

Russian authorities have begun handing jail sentences to activists on protest-related charges after they took to the streets in support of fair elections this summer.

Observers have compared the case to the aftermath of mass anti-Kremlin demonstrations in 2012, when dozens of activists were prosecuted and jailed in what has become known as the “Bolotnaya Square case.”

Here’s a brief overview of those who have been sentenced as of Oct. 9:

— Ivan Podkopayev, 25, originally sentenced to three years in jail after a court convicted him of pepper-spraying police. His sentence was commuted from three to two years on Oct. 9.

— Danila Beglets, 27, sentenced to two years after a court convicted him of grabbing a police officer by the wrist. His sentence was upheld on Oct. 7.

— Kirill Zhukov, 28, sentenced to three years after a court convicted him of lifting a police helmet visor. His sentence was upheld on Oct. 9.

— Yevgeny Kovalenko, 48, sentenced to three and a half years after a court convicted him of throwing a trash can at a riot police officer.

Both Podkopayev and Beglets pleaded guilty to using violence against law enforcement authorities, and both are still under investigation for mass civil unrest.

— Pavel Ustinov, 23, sentenced to three and a half years after a court found him guilty of dislocating a riot police officer’s shoulder. A Moscow court on Sept. 30 gave Ustinov a one-year suspended sentence with two years’ probation and reduced the severity of his charges from serious to moderate.

Ustinov's sentence sparked widespread public outcry after video footage showed him standing by a metro station as riot police approached and detained him.

Who has had their charges dropped as of Oct. 9:

— Sergei Abanichev, accused of throwing a paper cup at the police.

— Daniil Konon, accused of coordinating protesters.
