Petro Andriushchenko, an advisor to the Mariupol mayor, said that the local Ukrainian authorities discovered the second "filtration prison" near the city in what used to be a penal colony in Volnovakha, Donetsk Oblast. Over 20 volunteers who helped evacuate Mariupol residents to the Ukrainian-controlled territory are being detained there, he said.
