An off-duty Lewisville police officer was arrested Friday morning in Heath on a charge of sexual assault of a child, authorities say.
Zacur Vargas, 32, was taken into custody after officers with the Heath Department of Public Safety responded to a 911 call reporting suspicious activity about 6 a.m., according to the department. Officers found Vargas and a 16-year-old engaged in sexual activity in a public place, police said.
Vargas was booked into the Rockwall County Jail, where he was formally charged. The criminal investigation is being handled by the Heath Department of Public Safety and Rockwall County authorities.
Lewisville Police Chief Brook Rollins said Vargas was off duty, not in uniform and not engaged in Lewisville Police Department business at the time of the incident.
Following the arrest, the Lewisville Police Department opened an internal affairs investigation and placed Vargas on administrative leave, Rollins said.
Vargas has been employed by the department since May 2025 and is assigned to the Patrol Division.
