A woman is suing the Aaron Family Jewish Community Center of Dallas, alleging that her 14-year-old daughter was molested and raped repeatedly by a fitness center employee.

The mother, who is not named in the lawsuit, says she only knew that the man was harassing her daughter when she complained several times to the center's staff.

She alleges that when she confronted CEO Artie Allen about the employee's behavior and rumors that her daughter was dating the 24-year-old, Allen told her, "It takes two to tango."

Allen, who is also being sued, along with the Jewish Community Center Association of North America, declined to comment.

The lawsuit filed this month says the assaults started in 2014 after the teen was stalked by the employee, who trained the girl at the the facility's gym.

The employee is not named in the suit, but 24-year-old Randy Lee Adrian was arrested in August on two charges of sexual assault of a child. Police said Adrian is suspected of sexually assaulting a teenager he met while working at the Aaron Family Jewish Center.

Police said Adrian asked for the girl's number to text her diet plans and workouts, but began sending her explicit photos before sexually assaulting the teen over a span of 10 months. They said he also threatened to kidnap her and hurt her family if she told anyone about the assaults.

According to the lawsuit, the girl met the employee in the center's gym and he stalked, molested, sexually assaulted, threatened and raped her at the center and off-site repeatedly.

The Dallas center released the following written statement in response to the lawsuit:

"The JCC is aware of the lawsuit. It takes the matter seriously and will respond accordingly. The JCC is committed to understanding the full and relevant story by a thorough investigation. With a pending lawsuit, the JCC has no further comment at this time."

During the time the girl was being assaulted, members of the center complained to the staff about the employee's conduct, including two other girls who told the center's staff that he had sexually harassed them, according to the lawsuit.

Nothing was done about the employee's behavior and no investigation was launched, the lawsuit alleges.

The lawsuit also said the employee, whose job was to assist with equipment in the fitness center, was unlicensed and unqualified to be a personal trainer.

He would walk "around the fitness center sharing New Testament scriptures with members, purportedly seeking to share his Christian faith [with the girl] and other minor members of the JCC of Dallas."

The employe is in jail awaiting trial and is being investigated in several counties, the suit says.
