All programs serving inmates on supervised release following a prison sentence shall notify the appropriate probation officer, appropriate law enforcement agency, and the Department of Corrections within two hours after an inmate in the program fails to make a required report or after program officials receive information indicating that an inmate may have left the area in which the inmate is required to remain or may have otherwise violated conditions of the inmate’s supervised release. The Department of Corrections and county corrections agencies shall ensure that probation offices are staffed on a 24-hour basis or make available a 24-hour telephone number to receive the reports.
