Slidell police arrested four women on prostitution allegations at three massage parlors Friday night following an undercover investigation that was triggered by complaints from the public, spokesman Daniel Seuzeneau said Monday.

Undercover officers went into the businesses posing as customers, while other officers were standing by to make arrests. The investigation concluded that the women were giving erotic massages to several customers, Seuzeneau said.

Haiping Huang, 53, of Brooklyn, New York, and Xiaoyan Chen, 46, of Slidell, were arrested at Relax Therapy Massage, 1350 Corporate Square Drive.

Suwei Li, 48, of Slidell, was arrested at Super Relax Massage, 3675 Pontchartrain Drive.

Tian Jing, 48, of Miami, was arrested at To the Moon and Back Massage, 1501 Gause Blvd.

The investigation is continuing, Seuzeneau said, and police are looking into the ownership of the businesses.

The findings of the investigation have also been turned over to Slidell's code enforcement department and the Louisiana Board of Massage Therapy for possible further action, he said.

Asked if the activity might involve human trafficking, Seuzeneau said that is a "hot button topic" but one that is hard to prove.

This isn't the first time the police have gone to the massage parlor on Gause Boulevard. It was robbed in November when it was operating under the name Number 1 Massage Spa. The victim, who worked there, told officers that a man had entered the business and asked for a massage but brandished a gun and demanded money afterward.

Police released a surveillance video showing the man, but no arrest was ever made in the case, according to Seuzeneau.

The St. Tammany Parish Sheriff's Office busted a massage parlor in the Mandeville area last year after receiving "numerous complaints of illegal activity." The Sheriff's Office arrested a 53-year-old Kenner woman, booking her on prostitution by massage.
