"I've met with Pavlo Hryb. He looks okay, but is worried he doesn't have his medicines. Everyday needs haven't been addressed yet too," Andrei Sabinin wrote on Facebook on Monday, September 11.

The lawyer said the circumstances of the detention and other information in the Hryb case are classified. "I signed a non-disclosure agreement, therefore I cannot comment on the accusations," he wrote.

"According to Hryb, he was kidnapped by unknown persons in Gomel and handed over to other unidentified people, and a detention report was filed in Smolensk region about two days after. After that, he was brought to Krasnodar," Sabinin said.

According to previous reports, the lawyer was first not allowed to visit Hryb.
