The Cebongan Prison raid was an action undertaken by members of Indonesian Army special forces (Kopassus) when they attacked Cebongan Penitentiary Institution (Lembaga Pemasyarakatan Cebongan or LP Cebongan) in Sleman Regency, Special Region of Yogyakarta, Indonesia, on 23 March 2013. Four detainees suspected of murdering a former Kopassus sergeant were killed in the attack. The National Commission on Human Rights (Komnas HAM) investigated and concluded that the attack had been a human rights violation, though this was disputed by Defense Minister Purnomo Yusgiantoro.[1]
