A French researcher who is serving a three-year prison sentence in Russia is now under investigation for possible spying, according to court documents seen by AFP on Wednesday.
Filings show that Laurent Vinatier is scheduled to appear in court on Aug. 25 as part of an espionage case, charges that carry a maximum sentence of 20 years in prison.
Vinatier, who worked for a Switzerland-based conflict mediation organization, is just one of several Westerners who have been arrested in Russia amid heightened tensions over the full-scale invasion of Ukraine.
The French government has demanded that Russian authorities release him and accused Moscow of taking Westerners hostage.
Vinatier was jailed last October on allegations that he gathered information on the Russian military and violated the country's "foreign agent" law by not registering in a Russian government database.
Vinatier worked as an adviser at the Center for Humanitarian Dialogue and is a veteran researcher on Russia and other post-Soviet countries.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.

Remind me later.
