In a desperate attempt to escape, five defendants charged with multiple murders wrested weapons from their escorts Tuesday at a Moscow courthouse, sparking a shootout with other guards in the building's corridors.
Five of the accused "attacked police officers (escorting them) and tried to seize their weapons", while in an elevator, police said.
Three law enforcement officials were also wounded, said Petrova and Yevgeny Kubyshkin, a spokesman for the Russian National Guard, which had an officer in the court.
The members of the GTA Gang are charged with the murders of vehicle drivers in the Moscow and neighboring Kaluga regions in 2012 and 2014.
"There was a shootout in the Moscow Regional Court, employees were wounded, I saw a wounded female bailiff, whose face was covered in blood", Rubasskaya said. Three of them are police and National Guard officers. "They are in critical condition", the source said adding that both of them sustained gun wounds.
The regional court was evacuated for about an hour before operations resumed in the building. The defendants then somehow managed to disarm the guards.
Information about the death of the fourth member of the GTA gang has not been confirmed by the authorities yet.
Defence lawyer Diana Tatosova said she was told by the chief investigator that four of the 11 people standing trial had been killed.
The G.T.A. gang - which largely consists of men from the former Soviet republics in Central Asia - was behind a series of murders in the Moscow area in 2014.
