Houston Man on Probation for Child Sex Abuse Arrested for Aggravated Sexual Assault of a Child

Isaac Penilla, 26, has been arrested and charged with Aggravated Sexual Assault of a Child Under 14, following an outcry from a 12-year-old victim in the 2000 block of W. Thorne Drive near Westfield.

Deputies with Constable Mark Herman’s Office responded to an assault report, leading to the victim’s disclosure of sexual assault by a family friend. Detectives from the Special Victims Unit took over the investigation and identified Penilla as the suspect.

Further investigation revealed that Penilla was already on probation for Sexual Performance by a Child. He was apprehended without incident on May 23, 2025, and subsequently booked into the Harris County Jail. His bond has been set at $200,000.00 out of the 262nd District Court.

Authorities are urging anyone who believes they may be a victim of Isaac Penilla to contact Constable Mark Herman’s Office directly at 832-927-6188.
