Certificate of No Criminal Conviction (CNCC)

i think u have better chance in getting ur answers by asking the force directly.

Dun think any forumers here have that indept information to share. even so, it may contravene the OSA.

most of your questions are pertaining to police procedures and they are will not readily release such info.

its better to start off asking a moderately ranked police officer to get a "rough" picture.

then ask the police indepth of the Rough picture..

or post in the Police forum found in sgforums.
