MOSCOW  - Russian investigators said Friday that they had launched a fraud probe against opposition leader Alexei Navalny and his brother, putting new legal pressure on the protest movement’s most charismatic figure. The new probe - the second major investigation launched against Navalny - also comes as the opposition plans an unsanctioned rally Saturday in Moscow after the City Hall denied to authorise their proposed routes. Navalny and his brother Oleg “embezzled 55 million rubles ($1.8 million) from a trading company” and transferred some of the money to another firm they owned to launder the funds, the Russian Investigative Committee (SK) said.
