ARLINGTON- A local chapter of the Boys and Girls Club faces allegations of negligence after the family of a 12-year-old special needs child says she was sexually assaulted during one of the club's after school programs.

Longtime Fort Worth attorney Tom Hall represents the family.

"The innocence of this poor child has been taken from this child at a young age. She may be 12, but she is five mentally," Hall said.

According to a petition filed last week in Tarrant County District Court, the young girl was in a Boys and Girls Club of Arlington after school program in April of 2016 when she and another child ended up unsupervised at a drinking fountain.

From there, court documents allege that the boy "...ordered the minor plaintiff into the restroom. While in the restroom, the male student again ordered the minor plaintiff to pull down her pants [...] and sexually assaulted the minor plaintiff."

Hall says the boy, 13, also suffers from cognitive disabilities, and that club staff was negligent.

"The girl didn't get supervised, the boy didn't get supervised, and both sets of those parents paid money for supervision," he said.

A representative for the club said they couldn't discuss the case or allegations.

Arlington police say they did an initial investigation and passed along the case to the Tarrant County District Attorney's Office.

Hall says the girl's already underdeveloped mental capacity has been further damaged by trauma from the alleged incident, even a year later.

"She's still crying, she's still having nightmares, and she doesn't want to go back," he said.

At the time, the program was using facilities at an Arlington elementary school on South Davis Drive. Hall's office says the club is no longer there.

It wasn't immediately clear Monday night where the case stood with the district attorney's juvenile office.
