Two Southern California men were arrested after investigators uncovered a brothel operating in an Irvine neighborhood, police reported on Oct. 18.

The officers were investigating suspicious activity at a home in Cypress Village, about 40 miles south of Los Angeles, after someone reported finding fliers on nearby cars advertising prostitution.

The fliers advertised “pretty Asian and Latina girls” who were available for “sexy time,” and included a phone number and address of the house, Irvine police Sgt. Karie Davies told The Epoch Times.

“Officers went out and noticed some suspicious activity at the house and then they were able to get a search warrant,” Davies said.

Investigators said they uncovered what appeared to be a sex trafficking operation.

Qiyin Jiaqiyin, 51, of Irvine, and Xiaoming Ding, 36, of Whittier were arrested and booked into the Orange County Jail. The two men face sex trafficking charges with an enhancement that increased bail for each to $500,000.

They remained in custody as of Saturday, Davies said.

“Thank you to the witness who reported this suspicious activity to us,” the police department wrote on an Instagram post.

Three adult victims found at the house were offered assistance and released at the scene, Davies said.

Other California law enforcement agencies have also made sex trafficking arrests this year.

Federal, state, and local authorities are joining forces to combat human trafficking in the Figueroa Corridor of South Los Angeles, an area known for prostitution, they announced last month.

Also last month, Sacramento County authorities arrested 122 people and rescued two juveniles during a two-day sex trafficking operation.

The suspects faced charges related to prostitution, solicitation, and trafficking.

Sheriff Jim Cooper praised “Operation FAFO (fool around and find out),” saying the department would continue to target human traffickers.

“This sting sends a clear message to those involved in the illegal sex trade: We are committed to protecting our community from exploitation, especially our most vulnerable,” Cooper said in a September statement.

Prostitution and solicitation are misdemeanors in California.
