A report by the OHCHR Office of the United Nations High Commissioner for Human Rights that was released on 2 March 2015 described media postings and online videos which indicated that the pro-Russian armed groups of the Donetsk People's Republic carried out "summary, extrajudicial or arbitrary executions" of captured Ukrainian soldiers. In one incident, corpses of Ukrainian servicemen were found with "their hands tied with white electrical cable" after the pro-Russian rebel groups captured Donetsk International Airport. In January one of the self-proclaimed leaders of the Donetsk People's Republic claimed that the rebel forces were detaining up to five "subversives" between the ages of 18 and 35 per day. A number of captured prisoners of war were forced to march in Donetsk while being assaulted by rebel soldiers and onlookers. The report also said that Ukrainian law enforcement agencies had engaged in a "pattern of enforced disappearances, secret detention and ill-treatment" of people suspected of "separatism" and "terrorism". The report also mentions videos of members of one particular pro-Russian unit talking about running a torture facility in the basement of a Luhansk library. The head of the unit in question was the pro-Russian separatist commander Aleksandr Biednov, known as "Batman" (who was later killed) and the "head" of the torture chamber was a rebel called "Maniac" who "allegedly used a hammer to torture prisoners and surgery kit to scare and extract confessions from prisoners".
