Russia probes Navalny ally for 'threatening suspected poisoner'

Russian authorities on Friday launched a criminal probe into an ally of Kremlin foe Alexei Navalny after she tried to doorstep the apartment of a man Navalny said took part in his poisoning.

Investigators accused Lyubov Sobol of trespassing "with the use of violence or a threat to use it" after she rang the doorbell of the alleged agent from Federal Security Service (FSB), the country's main security agency.

The charges carry a maximum penalty of two years in jail.

Sobol was initially taken in for questioning as a witness in the probe, but later on, Friday Navalny ally Ivan Zhdanov said she became a suspect in the case.

"Lyubov Sobol is now officially a suspect in the criminal case, her status has changed," Zhdanov wrote on Twitter, adding that she was being taken into police custody for 48 hours.

Sobol's lawyer Vladimir Voronin confirmed this information to AFP without providing further details.

Russia's Investigative Committee -- which probes major crimes -- said in a statement on Friday that Sobol and several others repeatedly tried to enter the "apartment of an elderly woman" in eastern Moscow, adding that they were wearing uniforms of the country's consumer watchdog.

The statement said that Sobol tricked a delivery courier into letting her inside the apartment block and then forced her way into the woman's flat when she opened the door.

Just after 7:00 am (0400 GMT) on Friday, the 33-year-old opposition activist posted a video on Twitter from inside her apartment before going incommunicado.

In the video her seven-year-old daughter can be heard crying as someone pounds on the front door, demanding it be opened.

A separate CCTV image released by Navalny's allies shows masked men in black uniforms -- one carrying a crowbar -- inside Sobol's Moscow residential building.

Investigators confiscated Sobol's tech devices as well as her daughter's mobile phone, her associates said.

On Monday, Navalny said he had tricked an alleged chemical weapons expert with the FSB named Konstantin Kudryavtsev into admitting the domestic intelligence agency had sought to kill him this summer by placing poison in his underwear.

Later Monday, Sobol went to the Moscow apartment where Kudryavtsev is believed to live. She was detained by police at the scene and questioned for hours.

Sobol's lawyer said the probe had been launched following a complaint from Kudryavtsev's mother-in-law.

Western governments say Navalny, 44, was poisoned with the Soviet-era Novichok nerve agent in a case that has further dented Moscow's relations with leading European countries and sparked mutual sanctions.

The FSB says Navalny's call with Kudryavtsev was "fake" but has not denied that he works for the agency.

The Kremlin has admitted that security agents have tailed Navalny but denied any attempts to poison him.

Russian authorities have not opened a criminal probe into the opposition leader's poisoning.

Navalny said the Russian authorities' "hysterical reaction" only proved their guilt.

"You call a killer's doorbell -- they break down your door and take you in for questioning," he wrote on his blog.

Sobol, a lawyer by training, has announced plans to run in parliamentary elections next year.

She rose to prominence in the summer of 2019 when she and other opposition politicians were barred from running for local council elections in Moscow.

The barred candidates spearheaded demonstrations in the Russian capital over their exclusion from the polls and Sobol also staged a month-long hunger strike in protest.

Kremlin critics have accused authorities of taking a crackdown on the opposition to new highs in recent months.

But Navalny, who is undergoing physical therapy in Germany, said late Thursday he was as optimistic as ever.

"I am absolutely convinced that we will prevail," he said during a YouTube broadcast hosted by Sobol.

"And even though life puts a bit of pressure on us we will come out even stronger."
