Rail maintenance foreman Valery Bashkatov, who was detained over the recent devastating crash in the Moscow subway that killed 22 people, is escorted handcuffed in a court in Moscow, on July 17, 2014. City authorities declared yesterday a day of mourning after the worst accident in the metro's eight-decade history, while Muscovites swapped stories of how the authorities had ignored their complaints about the overcrowded system.
