Russian protest leader Alexei Navalny leaves the offices of the Russian Investigation committee in Moscow, Russia, Tuesday, July 31, 2012. Russia's top investigative agency says it has opened a new criminal probe against opposition leader Alexei Navalny on allegations of theft. The 36-year-old corruption-fighting lawyer and popular blogger has played a key role in rallying Russia's young Internet generation against Vladimir Putin's rule.
MOSCOW — Russia's opposition leader Alexei Navalny says he has discovered a listening device in his office in central Moscow.
Navalny, one of President Vladimir Putin's fiercest critics and a driving force behind last winter's mass protests, posted a photo of the listening device on his Twitter on Monday.
Police officers were working at Navalny's offices to investigate how the device got planted there.
The 36-year-old anti-corruption activist was charged last month with theft for allegedly organizing a plan to steal about $500,000 in assets from a state timber company. He was ordered to remain in Moscow as authorities investigate him. Navalny has denied the charges.
