According to the Cheka-OGPU and Rucriminal.info, Olga Kolishchuk, a socialite and organizer of an art and antiques investment project, was detained in Moscow. She has been placed in pretrial detention.
According to a source, Kolishchuk was detained in Moscow and then transferred to Rostov-on-Don. The city's Leninsky District Court ordered her pretrial detention. The arrests were part of an investigation into auction fraud linked to Kolishchuk's Mitra Group and the Tender Standard trading platform.
The socialite made her fortune by selling bankrupt assets, creating a dedicated platform called viomitra. This platform later added a division for selling art and antiques. Kolishchuk actively participated in social events in Moscow and held various auctions. The most recent of these took place in October 2025, at the Muravyov-Apostol Museum-Estate.
Kolishchuk is also Vice President of the National Union "National Association of Electronic Trading Systems" and Director of the Self-Regulatory Organization of Electronic Platforms.
