Several sources have reported 610 officers as being involved in or ordering the torture of Falun Gong adherents in custody. In a letter to Chinese leaders in 2005, prominent human rights lawyer Gao Zhisheng relayed accounts of 610 officers beating and sexually assaulting Falun Gong practitioners: “of all the true accounts of incredible violence that I have heard, of all the records of the government’s inhuman torture of its own people, what has shaken me most is the routine practice on the part of the 6–10 Office and the police of assaulting women’s genitals,” wrote Gao.[1][25] Defector Hao Fengjun described witnessing one of his 610 Office colleagues beating an elderly female Falun Gong practitioner with an iron bar.
