LOS ANGELES (CNS) — Almost three-dozen missing children — including eight who were being sexually exploited at the time of recovery — have been found in the Southland during a recent operation, the FBI announced.

During January, which was Human Trafficking Awareness Month, the FBI worked with the Los Angeles Police Department, the Los Angeles County Sheriff's Department and more than two-dozen law enforcement and non-governmental partners to identify, locate and recover 33 missing children, Kristi K. Johnson, assistant director in charge of the FBI's Los Angeles field office, said Saturday.

Exact details about the operation, nicknamed "Lost Angels," were not available.

Of the children recovered, eight were being sexually exploited at the time of recovery. Two were recovered multiple times during the operation while on the "track," a term commonly used to describe a known location for commercial sex trafficking, Johnson said.

Several of the victims had been sexually exploited in the past and were considered vulnerable missing children prior to their recovery. Additionally, the operation resulted in the arrest on state charges of one suspected human trafficker and the opening of multiple investigations. Some of the minor victims were arrested for probation violations, robbery or other misdemeanors, and one child was a victim of a non-custodial parental kidnapping, according to the FBI.

The FBI case load for both sex and labor trafficking-related crimes has increased significantly in the past several years. As of November, there were more than 1,800 pending trafficking investigations including those involving minors exploited through commercial sex trafficking, according to the agency.
