Police Intelligence Department (PID)
It started as the Criminal Intelligence Unit (CIU) of the Criminal Investigation Department on 1 April 1973 to support CID's investigations. To reap greater synergies and for better intelligence collation across the entire SPF, the CIU was revamped and upgraded to a division of CID in October 1988; and subsequently to a full-fledged Department on 28 Mar 1996.

The mission of the Police Intelligence Department is to provide useful intelligence to prevent, deter, and detect Crime in Singapore
