The multi-day joint agency "Operation Lost Angels" involved more than two dozen partner agencies and was initiated on Jan. 11. The rescue operation recently culminated in the recovery of 33 children, Kristi K. Johnson, assistant director in charge of the FBI's Los Angeles Field Office, said in a press release.

"Of the 33 children recovered, eight were being sexually exploited at the time of recovery," FBI officials said in a press release.

"Two were recovered multiple times during the operation while on the 'track,' a common term used to describe a known location for commercial sex trafficking."
