"A criminal procedure check is being conducted on the fact of bodily harm by a minor group of teenagers in the territory of the Kalininsky district of the city of Novosibirsk," the agency said.

According to RIA Novosti, earlier videos appeared on social networks with the beating of schoolchildren by a “gang of teenagers” who extorted money from children.

On November 24, two teenagers suspected of having committed a robbery with violence against a 15-year-old peer, who were subsequently hospitalized, were detained in Moscow. A criminal case has been instituted against young people.
