The Attica Correctional Facility is a maximum security/supermax New York State prison located in the town of Attica, New York, operated by the New York State Department of Correctional Services. After it was constructed in the 1930s, it held many of the most dangerous criminals of the time. A tear gas system is installed in the mess hall and industry areas and has been used to quell conflicts in these areas. The prison now holds many inmates who are serving various types of sentences (short-term to life), and who are usually sent to the facility because of disciplinary problems in other facilities. John Sullivan is the only man that has ever escaped the prison.
