In each case, the man stood outside his car and committed a lewd act in front of his victims. The incidents are becoming more frequent and that has police concerned.
"I think this is a person who needs to be addressed by the criminal justice system as quickly as possible," said Lower Providence Township Police Chief Francis Carroll.
"This is the only instance where we have any type of verbal communication between the victims and the suspect," said Carroll. "The suspect yelled profanities at the victim."
Investigators said the suspect spoke with a Middle Eastern or Indian accent.
The suspect is described as 25 to 40 years old, 5'5" to 5'10" tall, slender to medium build, short black hair, and clean shaven.
Women who spoke to Action News Friday said they will follow the advice of police to stay aware of their surroundings, with hopes the suspect is caught soon.
"Just more watchful, really, more watchful," said Patty Micolucci of Villanova, Pa. "I'll still be going because this is a nice place."
"He needs help desperately," said Pat Stibinski of Collegeville, Pa.
The suspect has not made any physical contact with the victims. Police say he may be driving a silver or gray sedan.
