DALLAS -- The head of the Latino police officers group has been put on restricted duty after his ex-wife’s boyfriend alleged that he punched him at his daughter’s school talent show.

Sgt. George Aranda was put on restricted duty Saturday night, pending an internal investigation. Aranda who spoke to WFAA said it just did not happen.

“I’m not going to jeopardize a 25-year career,” said Aranda, president of the National Latino Law Enforcement Organizations' Greater Dallas chapter.

The allegation comes just days after Aranda and several other police association leaders demanded an outside investigation into what they’re calling a “cover-up” by two of the department’s highest-ranking officers.

They are alleging that Dallas Police First Assistant Chief Cynthia Villarreal, the highest ranking woman and Latina on the force, improperly handled a domestic incident between Dallas Police Assistant Chief Christina Smith and Smith's boyfriend.

According to Aranda, he attended his daughter’s talent show contest Thursday night. He says his sister, two nieces and son were with him and can attest that no assault occurred.

After his daughter performed, he says he gave her roses and told her he was leaving. He said he then walked over to his ex-wife and whispered in her ear that his son would be riding home with her.

He says at that point, the boyfriend jumped up out of his seat and looked at him. Nothing was said between them, Aranda said.

Aranda says he then left with his sister and nieces.

The next morning, he says he went to his ex-wife’s house to pick up his children to take them to school. Again, he says nothing was said about the alleged assault. It wasn’t until late that morning that he says his ex-wife texted alleging that he had hit her boyfriend.

“I was like, ‘What are you talking about?’ I haven’t punched anybody,” he said. “Nobody hit anybody.”
Aranda says that the boyfriend is a former Dallas police officer who had blamed Aranda for the department’s decision not to rehire him.

“This guy knows the system,” he said. “The truth will come out.”
