Parents of the girls alerted Webster police that a man had been taking pictures. One witness told police he'd seen this man taking photos of girls playing at parks on many occasions.
Webster police arrested Clark at 7:15pm Wednesday. Clark is accused of photographing the children without consent with the intent to arouse and gratify a sexual desire.
Police seized computer equipment from Clark's car, including a digital camera, memory cards, an iPod, USB flash drives, a computer and a collection of pornographic materials. The evidence was submitted to the district attorney's office.
