MOSCOW (AP) — Moscow police have arrested the brother of jailed Russian opposition leader Alexei Navalny after carrying out a series of raids on apartments and offices belonging to the politician’s family and associates. The places searched on Wednesday included Navalny’s apartment, where police detained his brother, Oleg, and a rented apartment where Navalny’s wife, Yulia, has been living. Other locations raided by police were the offices of Navalny’s anti-corruption foundation and the studio that produces his videos and online broadcasts. The popular videos and broadcasts helped make Navalny into Russian President Vladimir Putin’s most prominent and persistent foe. The raids came four days before protests that Navalny’s supporters have called for Sunday.
