A Broussard mom asked the Lafayette Parish School System to investigate her claim of "aggressive" handling of her autistic 3-year-old son by an elementary school principal after police declined to pursue charges.

Brenna Primeaux said she became concerned Thursday while attending her daughter's pre-K graduation at Katharine Drexel Elementary School. She brought her son, Arley, and her 4-month-old to their big sister's graduation.

She said Arley was overstimulated by the crowd and the noise, so she took him and the baby outside during the ceremony.

She said Principal Denise Soileau asked her not to allow the boy to run around and that when he started to play again the principal "grabbed him by both wrists, swung him around and yelled in his face."

"I could see in his face he was terrified," Primeaux said in an interview.

She brought her child back inside for the ceremony and then she returned outside to talk to the principal.

"When I got outside I told her not to touch him again," Primeaux said. "She told me to leave the premises and denied touching him."

Primeaux said she missed seeing her daughter receive her diploma because she was told to leave. She later filed a complaint with police.

Upon hearing no charges would be filed Friday, she made a public post on Facebook about the incident and urged others to join her to complain.

"It's not okay for anyone to put their hands on a child, especially one with special needs!" she wrote.

"No child should be touched without permission, especially aggressively," Primeaux said in an interview, also adding "especially" those with special needs like her nonverbal son.

"He can't express when he's scared," she said.

Soileau could not be reached for comment Friday.

Primeaux also contacted the Lafayette Parish School System to file a complaint against the principal.

As part of its investigation, the school district obtained video from school cameras that recorded the incident, reviewed the video and turned it over to Broussard Police, said Larry Alexander, director of career and technical education and magnet schools for LPSS.

"Police determined there was no malicious intent and no criminal activity and decided no charges would be filed," Alexander said.

The district is investigating "to make sure all procedures were followed," he said. There has not been an official ruling on the incident.

"From my perspective, (in the video) it looks like the principal was concerned about the safety of the child," Alexander said.
