“Today at 7 am the police came to Lyubov Sobol’s apartment,” the team wrote in a Twitter post on Friday. “Since 7:10 Sobol has not been in touch, and the cameras in her apartment were sealed and turned off.”
Police seized all the electronics belonging to Sobol, to her husband and to daughter, Navalny’s team said.
Ivan Zhdanov, head of Navalny’s Anti-Corruption Fund, wrote on Twitter that investigators launched a probe into trespassing “with the use of violence or a threat to use it” after Sobol rang the doorbell of the FSB agent.
Russian authorities have not officially announced that a case has been opened.
Navalny fell ill on a plane to Moscow and was eventually taken to Germany for treatment. He ultimately survived the attempt on his life.
The anti-corruption activist has accused the Russian state of involvement in the poisoning.
The Kremlin denies any wrongdoing.
