Russian officers again detain opposition leader Navalny

Security officers in Moscow have again detained Alexei Navalny, the most prominent foe of President Vladimir Putin and the governing United Russia party.

Navalny has been jailed repeatedly in recent years for organizing or participating in unsanctioned protests. His Foundation for Fighting Corruption organization has produced reports alleging corruption by top figures including Prime Minister Dmitry Medvedev.

Navalny was detained when officers forced their way into his organization's office Thursday, according to his spokeswoman Kira Yarmysh.

Lyubov Sobol, an attorney with Navalny's foundation said the officers were from the federal court bailiffs' service and that they claimed to be searching for evidence connected to a case against the foundation's director, Ivan Zhdanov.

A criminal case was opened against Zhdanov in August for failing to follow an order to remove a video version of a report claiming corruption by Medvedev.
