Complaints Investigation Unit (CIU)

The Complaints Investigation Unit (CIU) is an independent establishment appointed by the Commissioner of Correctional Services (CCS) to handle and investigate all complaints within its purview expeditiously, thoroughly and impartially under the ISO Quality Management Systems aiming at redressing grievances, preventing similar complaints and bringing continual improvement in overall service quality.

For check and balance, Correctional Services Department Complaints Committee (CSDCC) is vested with the authority to examine all investigation findings handled by CIU.

CIU will endeavour to complete its investigation of a complaint within 18 weeks and submit the investigation report to CSDCC for examination. After endorsement of the outcome of the investigation by CSDCC, the complainant will be informed of the outcome in writing accordingly. If the outcome is not endorsed, the complainant will be notified in writing of the progress regularly until endorsement of the outcome by CSDCC.

A complainant who is dissatisfied with the outcome of the CIU investigation may apply in writing for appeal to Correctional Services Department Complaints Appeal Board (CSDCAB).

Complaints/opinions about any staff or policy of Correctional Services Department may be lodged with CIU in person, by phone, by fax, by email or in writing.
