I had personally seen an AV raid at IP. That day got an av officer posed as customer sitting at the lounge area at around 2 plus. I think he was the one signalling the others to begin the ops. Luckily haven't gone in yet as it happened very fast & Out of the sudden, there are 4 officers including 2 females knocking the doors. 4 gals were caught & those caught customers were seen having their statements taken down.
I think once got pple kenna caught, the av would continue ops until none was nabbed.
