Thirty people were arrested and four girls were rescued in a crackdown on human trafficking activity in Compton, authorities said Saturday.

The operation was conducted Thursday by the Los Angeles County Sheriff’s Department as part of the Los Angeles Regional Human Trafficking Task Force.

During the operation, detectives arrested 30 adults and rescued four females they identified as “commercially, sexually exploited children,” said sheriff’s Lt. Barry Hall.

The four children were released to the care of the Department of Children and Family Services, Hall said.

Ten of those arrested were adult female sex workers who solicited undercover deputies for various sex acts, Hall said. Six of those arrested were booked on charges of loitering for the purposes of prostitution, he added.

All of the females were offered victim-centered services from the Restoration Diversion Services, a local service provider from Compton, according to Hall.

Thirteen men were arrested for allegedly soliciting undercover deputies for various sex acts and those men were booked at the Century Regional Detention Facility.

Authorities identified one man, 27-year-old Lafayette Lomax of Compton, who was arrested on felony charges of pandering after he attempted to have an undercover deputy work for him as a prostitute, Hall said.

Authorities also identified a 70-year-old Carson man, Robert King, who was arrested on a felony warrant for sex crimes against children, according to Hall.
