Orange County resident James H. Knuth, age 71, of Pine Bush, was arrested on Monday, April 24.
In February, detectives from the Ulster County Sheriff's Office initiated an investigation into Knuth after it was alleged he had been in communication with a social media account pretending to be a juvenile girl for several months, said Sgt. Collin Reynolds, of the Ulster County Sheriff's Office.
The communication was sexually explicit in nature, Reynolds said. Knuth was also found in possession of numerous videos and photographs depicting sexually explicit content involving minors, he added.
The department was assisted in the investigation by the Ulster County District Attorney's Office, US Marshals Service, and the town of Shawangunk Police Department.
Knuth is being held at the Ulster County Jail.
