“I learned the name of PPC in which I was detained as PPC No. 15. I learned it after my arrival there. I don’t know why it was called No. 15. Everybody simply said it was ‘PPC No. 15’.” (A05, former prisoner from Ipsok-ni, PPC No. 15, 1976~1980) “There are about 20 areas in the county of Yodok, South Hamkyong Province, where the Yodok PPC is located. The Yodok PPC encompassed the five areas including Kuup-ni, Ipsok-ni, Yongpyong-ni, Pyongchon-ni and Taesuk-ni, representing one third of the entire county. Its official title was High-security Zone, Control Center No. 15, Yodok County, South Hamkyong Province.”(Kang Chol-hwan, former prisoner from Ipsok-ni, PPC No. 15) “Unit 7 was the center of Camp No.15. It was in Ipsok-ni. It included a shop, a clinic and schools and everything else. I watched as the prisoners who were detained there in the 70’s were all transported to the maximum-security zone at Yongpyong-ni. We were told that conditions in the maximum-security zone are much worse. The prisoners who were sent there were all landlords, capitalists, their children and other wicked elements. So there were only new arrivals in Ipsok-ni.” (A11, former prisoner, from Ipsok-ni, PPC No. 15, 1976~1980) “PPC No. 15 is located in the Yodok County, South Hamkyong Province, a mountainous area, with Maengsan on the west, Taehung County of South Pyongan Province on the north, Kumya County of South Hamkyong Province to the east and the County of Kowon of South Hamkyong Province to the south. Its official title is Yodok Control Center No. 15, South Hamkyong Province (PPC). I was detained at the Ipsok-ni area most of the time. 48
