A masked man rang a doorbell and threatened a homeowner with a large knife early Sunday morning, state police said.
It happened around 1:50 a.m. Sunday in the 1000 block of Village Round in Lower Macungie Twp., Lehigh County.
Authorities said a man wearing a mask similar to the one worn by Jason in the "Friday the 13th" movies pointed the knife in the direction of a 58-year-old woman who answered the door.
The man left the area, and nobody was injured, state police said.
He's described as a black male, about 6 feet to 6 feet 4 inches tall with short black hair. He was also wearing a dark-colored jumpsuit.
Anybody with information is asked to call police.
