In this file photo taken on Wednesday, June 13, 2012, anti-corruption blogger Alexei Navalny speaks to the media as he arrives for questioning at the headquarters of the Russian Investigation committee in Moscow, Russia. Oppositionist Alexei Navalny, who was elected in the Aeroflot Board of Directors, intends to protect the interests of this company and the rights of its minority shareholders. He has made an entry to this effect in his LiveJournal.
Alexei Navalny's quarter of a million Twitter followers on Tuesday found abusive messages pouring from his account.
Navalny linked the hackings to his personal computer and iPad being seized by police in a raid on his apartment on June 11.
The 36-year-old opposition leader has been at the forefront of the anti-Putin protests. His home and office were raided and he was interrogated several times as part of a probe into the violence at an opposition rally on May 6.
His spokewoman, Anna Veduta, said Tuesday that Navalny hopes to regain access to his accounts.
