A five-year veteran of the San Antonio Police Department now stands accused of sexually assaulting a girl on a nearly weekly basis for roughly four years.

47-year-old Juan Ruiz-Carrillo was arrested Monday night and charged with sexually assaulting a child.

He’s suspected of assaulting the girl nearly every week, starting when she was just 15 years old. Authorities say the girl told a youth pastor at her church about what was going on.

He’s since been placed on administrative leave pending the outcome of this case.
