"The detainee crossed the state border of the Russian Federation beyond the established check points; he had no ID on him," reads the statement.

Besides administrative proceedings for violation of the regime of the Russian state border, the Russian authorities consider launching criminal proceedings against the Ukrainian citizen for illegal crossing of the Russian border.
