Police in Cumberland County are investigating three reports of a man looking into the windows of Upper Allen Township homes.
Township police said Thursday that the incidents occurred over the course of a week, with the third incident occurring December 20 in the 1800 block of English Drive.
The prowler was described as being younger and thin, police said.
Each time, the man was seen loitering around occupied residences and looking in windows in the area of English Drive and Wyncote Court.
