Police are looking for a man who exposed himself to two women on the Shank Park walking trail in Hummelstown.
Derry Township police said the women heard someone whistling at them and turned to see the naked man standing near a tree line and waving to them.
He then disappeared into the tree line and went to a nearby parking area where he was seen leaving in a dark blue SUV, possibly a Chevrolet Yukon or Suburban, just after 10 a.m. Tuesday, police said.
The SUV was said to have a loud exhaust and possibly had a white license plate. It was possibly an older model, but in good condition, police said.
The man was believed to be about 40 years old, 6'0" tall, with an athletic build.
Anyone with information may call Derry Township police at 717-534-2202.
