STORY: Derhachi district mayor Vyacheslav Zadorenko said the cellar in Kozacha Lopan had been used to torture Ukrainian civilians.
Zadorenko claimed Russian forces detained people at the town's train station where they were beaten into making confessions before being transferred to the dingy cellar.
Iron bars, apparently recently welded together, form what look like cells with heavily barred metal doors behind which were grubby mattresses and bedding, discarded food tins, plastic plates, and water bottles.
The Derhachi district prosecutor's office opened an investigation in Saturday (September 17) accusing Russia of creating a "people's police" in Kozacha Lopan.
The prosecutor's office says the "people's police" created a cellar chamber in which they tortured civilians.
