Four young women were swimming and sitting on the rocks at the Buttermilk Falls. They observed a man watching them from the bushes, performing a lewd act on himself and making motions for them to come over to his location. The victims told him they were calling the cops and he took off on a bicycle. Steven Bitcko, 27, of Beaver Falls was located by police on State Route 18 and appeared to be under the influence of alcohol and narcotics. The accused was subsequently arrested and transported to Heritage Valley Hospital for testing. Charges will follow results.
