A Lewisville police officer has been arrested and charged with sexual assault of a child after allegedly being caught engaged in sexual activity with a 16-year-old in Heath, Texas.
Zacur Vargas, 32, was taken into custody around 6 a.m. on December 12, 2025, according to officials. The off-duty officer was reportedly discovered in a public place with the minor, leading to his immediate arrest by Heath Department of Public Safety officers.
“These allegations are extremely serious and deeply concerning,” Lewisville Police Chief Brook Rollins said in a statement. “As the facts are established, we will respond decisively in a manner that reflects our responsibility to the community.”
Off-Duty Conduct
Authorities have confirmed that Vargas was booked into the Rockwall County Jail following his arrest. The criminal investigation is now being handled jointly by the Heath Department of Public Safety and Rockwall County authorities.
Chief Rollins has emphasized that Vargas was neither in uniform nor conducting any official police business at the time of the alleged offense. The clarification came as the department faces questions about the conduct of one of its officers in a case involving a minor.
What happens next? The Lewisville Police Department hasn’t yet announced any internal disciplinary measures, though such actions typically follow the formal filing of charges in cases involving law enforcement personnel.
The arrest has sent shockwaves through the Lewisville community, where residents have expressed dismay over the allegations against an officer sworn to protect the public. Local officials are working to reassure citizens that such behavior isn’t representative of the department as a whole.
The criminal investigation remains active, with authorities indicating they’re working to gather additional evidence and determine whether there might be other potential victims.
For now, the case stands as a stark reminder of the heightened standards to which public servants are held — and the particularly serious nature of allegations involving those entrusted with upholding the law.
