The businesses were disguised as massage parlors that were advertised on websites know for prostitution, the Orange County District Attorney’s Office said.

“As operator/owner of the brothel, Tran collected a portion of the proceeds from sex services performed and provided condoms, lubricant and information on ways to avoid detection by law enforcement,” Lt. Jeff Hallock said.
