MIDTOWN — A Seventh Avenue spa boasting "sexy," lingerie-clad attendants was busted for selling sex when an undercover officer visited the parlor under the guise of seeking the illicit services.

The operation resulted in the arrest of two spa employees — an attendant who agreed to have sex with the undercover officer for $120 and a spa manager who facilitated the arrangement, police and prosecutors said.

The officer, who works with the Manhattan South Vice Enforcement Squad, came to Red 27 Spa on the second floor of 289 Seventh Ave. between 26th and 27th streets on June 2 around 7:15 p.m. and spoke to a manager sitting behind the front desk, according to a criminal complaint.

The manager led the officer to a small room with a massage table and told him it would be $120 for sex with one of her girls plus an additional $80 fee for the manager herself, the complaint states.

The manager then brought the attendant into the room, who agreed to have sex with the officer for $120, prosecutors said.

The manager, Yi Rong Wang, 43, was arrested and charged with promoting prostitution. She was released on her own recognizance after her arraignment and is due back in court June 13, court records show.

The attendant was arrested and charged by police with prostitution, but was given a desk appearance ticket and is scheduled for arraignment July 31, police said.

Red 27 Spa’s website is stocked with photos of scantily-clad “attendants” with blurred faces. They are billed as “young,” “hot” and sexy,” and descriptions often include their bra cup and waist sizes. Reviews from clients rave about the spa’s “sensuous” services and “good time[s].”

Wang’s attorney did not immediately return a request for comment. A woman who answered the phone at Red 27 Spa said she did not speak English then abruptly hung up. A spa employee did not immediately respond to an email requesting comment.
