Just days after the first anniversery of the death of Anna Politkovskaya, nine people, including a security services officer, have been charged over the murder of the journalist.
It is reported the officer is a lieutenant-colonel in the FSB and that he has been charged with abuse of office.
Russian media say he is alleged to have passed on details of the journalist’s address to another suspect who, it is claimed, gave them to the killer.
Politkovskaya, a fierce critic of President Vladimir Putin, was shot dead in October 2006 outside her appartment in Moscow.
Her killing caused an international outcry and put pressure on Putin to ensure the crime was solved.
