Police reportedly arrested 539 people in a week-long sex trafficking sting.

Law enforcement reportedly took several suspected sex traffickers into custody and saved various victims in California last week as part of the state’s 10th annual Operation Reclaim and Rebuild, ABC 7 reported.

Authorities arrested 40 suspected “sex traffickers or exploiters” and 271 suspected “sex buyers,” the outlet reported. There were 54 adults and 11 children rescued as part of the statewide initiative, including a 14-year-old girl, Los Angeles County Sheriff Robert Luna said.

“Human trafficking and child exploitation are devastating crimes that prey on some of the most vulnerable members of our community,” Luna said.
