A court in the Russia city of Samara on July 22 sent three teenagers -- two of whom were from Central Asia -- to pretrial detention until September 18 on an attempted-murder charge after a brawl last week with Mikhail Matveyev -- a member of the State Duma (Russia’s lower chamber of parliament). 

Current Time says the incident took place on July 18. 

Matveyev reportedly says he had been hit in the head with a glass bottle after he had tried to stop a brawl.

The Investigative Committee has initially instituted criminal proceedings against Tajik-Russian citizen Nekrouz Bakhirov and Uzbek citizen Murod Musurov, both 19, as well as a 16-year-old Russian national identified as Artur B., under the charge of hooliganism.  But later, by order of the Investigative Committee head Alexander Bastrykin the charge was changed to attempted murder.

The defense asked to place them under house arrest, but the court arrested three detainees until September 18.  

Some Russia media reports cited Matveyev as saying that he was assaulted by migrants when he tried to prevent them from assaulting a passerby.

Mikhail Matveyev is a Russian politician and historian. A member of the Communist Party, Matveyev represents the Promyshlenny constituency in the State Duma.

“There’s migrant mayhem on the streets,” Matveyev, with his head bandaged, said in a video published on his personal Telegram channel.
