A former serviceman opened fire in a public service office in Moscow after he was asked to put on a face mask, the Moscow police reported on Tuesday.

Two people were killed and four wounded in the shooting, including a 10-year-old girl, the police said in a statement.

The shooter, identified as Sergey Glazov, was arrested at the spot by a migration police officer.

Glazov was in a deranged condition while committing the crimes and he will be sent for a psychiatric examination, the police noted.
