Parole is the provisional release of a prisoner from imprisonment before full sentence has been served. Parole usually is granted for good behavior on the condition that the parolee regularly report to a supervising officer for a specified period. It is an alternative to imprisonment, rewarding offenders for complying with their sentence plan and participating in rehabilitation programs and combating recidivism by ensuring the gradual re-integration of offenders. If the parolee violates his parole condition he could be arrested and imprisoned to serve his full sentence in the prison.
