The woman thought responsible for a bomb blast in St Petersburg earlier this month has had her appeal rejected by a Russian court.
Darya Trepova, 26, appeared via video link from a detention centre for an appeal against her arrest on charges of involvement in the April 2 bombing that killed Vladlen Tatarsky and injured 50 others at a cafe in St .Petersburg.
Moscow City Court upheld a lower court ruling that ordered Trepova to remain in custody for two months pending investigation.
