GTA:Bolingbroke Penitentiary
Bolingbroke Penitentiary serves as the main prison in San Andreas. It is used by the police to lock up those who commit serious crimes and pose a threat to society. Within the prison there are many different areas including; a visitors center, an outside weights area in the yard and many cells. If the prison guards are feeling generous, they might give you yardtime so you can collect apples & oranges to make yourself a smoothie. But if you misbehave, you might get locked up into solitary.
The prison is managed by a private security company called Gruppe 6. They are usually armed and found within the prison monitoring the prisoners and the area around it.
