The audit of the Office of the Police Complaint Commissioner notes, however, that most investigations were not completed in the six-month time frame specified in the Police Act and needed extensions which were granted by the commissioner.
It also says the office should train staff working at police detachments on how to receive and handle complaints.
The audit was ordered by members of the B.C. legislature on May 13, and the auditor general was directed to complete the report by Jan. 1, 2013.
The auditor general looked at complaints and investigations concluded between April 1, 2010 and Aug. 31, 2012.
The auditor general says none of the complaints reviewed were treated as trivial.
