Russian investigators said on Wednesday that they had detained two Moscow metro workers in a probe into a devastating crash that killed 22 people and injured dozens.
The Investigative Committee said it was holding two suspects: a maintenance foreman, Valery Bashkatov, and his assistant Yury Gordov. "The detained have already been questioned," the committee said, noting the men will soon be formally charged with safety breaches.
