Glen Lennox is one of three neighborhoods where the suspected peeper was spotted as recently as Monday night. According to police, a man has been prowling the area, standing near windows, and in some cases, knocking to get someone's attention.
Resident Hart Moss told ABC11 he's known about a peeper for two years.
"We had already been getting fliers about someone who had kind of been lurking around windows, or hanging out in the back, or putting his hand up on showers, so we've been intermittently getting these fliers every few months," Moss explained.
Shari Headen said she also has heard about the peeper for quite some time.
"What I've heard so far is this fellow has been around for about a year," she said. "He's been peeping in windows. They've warned everyone to make sure the bathroom windows have a shade or curtain, something that covers the glossy window."
Male and female residents are concerned. Headen said her daughter is frightened by the situation as well.
"She's pretty scared," Headen added. "Me? I know that the next step for a Peeping Tom is really to enter a home. But I think with a dog, and with enough people, enough traffic in the house, I think that that may scare them away. I worry more about the single people, single women especially."
Although Moss said he's not as concerned, he feels differently about his wife.
"[It] concerns me that my wife is home alone at times," he said.
Chapel Hill police describe the male peeper as someone between 20 and 40 years old, 5'8" to 5'10", and with a thin build. He may be driving a dark colored sedan.
That's not a lot for residents to go on, but police said they are keeping an eye out for the suspect.
"You know, I just hope it doesn't turn into anything worse than that ever," Moss said.
Some residents said they've seen more police officers in the area.
Police ask residents to get a good description of any suspicious person and call them right away. They also warn people to always make sure doors and windows are locked.
