In July 1943, 374 political prisoners and POWs prisoners [mostly Yugoslav,] were brought to the concentration camp. They were tasked with widening the road to Karigasniemi, Finland. After four or five months, only 111 of these prisoners were still alive. At the end of the prisoners' stay in Karasjok, before transportation out of Karasjok, 45 prisoners were massacred by the firing of small arms. At least one former prisoner is (as of 2013) still alive.
