A Montgomery County man is accused of sexually abusing children and possessing child sexual assault material. The investigation began in December 2025 after police received information that a man was soliciting a girl for sexual acts and sexually explicit photos in the Willow Grove section of Abi ngton Township, Pennsylvania. Police later identified Deren Thach, 38, of Ambler, Pennsylvania, as the suspect and determined there were other underage victims. Resources for victims of sexual assault are available through the National Sexual Violence Resources Center and the National Sexual Assault Telephone Hotline at 800-656-4673. Police then executed a search warrant at Thach’s apartment on March 6, 2026. Investigators said they seized digital evidence and analyzed it for child sexual assault material. Thach was then charged with multiple counts of sexual abuse of children, corruption of minors, unlawful contact with a minor and other related offenses. Deren Thach Thach turned himself in to Abington Township Police on March 12. He was arraigned and his bail was set at $100,000 cash. NBC10 reached out to Thach’s attorney. We will include a statement once we receive one. Anyone who has additional information on the investigation or believes they were a victim of Thach should contact Detective Alison Gontowski of the Abington Police Special Victims Unit at 267-536-1113 or [email protected]. ...read more read less
