Cal Poly students living off campus say they've been getting unexpected visitors.
Peeping Toms or prowlers have been making them uncomfortable and concerned.
Students say these incidents have become a daily occurrence for some of those living off campus and say the Peeping Toms have not only been peeking through windows but have even been climbing on rooftops.
"I was never really afraid of it until I realized it's actually happening to everyone every single night and now we can't sleep at night, like, we stay up," said Victoria Cuce, Cal Poly student.
Cuce says she woke up around 5:00 in the morning one day to a flashlight pointed at her from outside her window.
"I stood up out of bed and I get closer and I realize that there's just a flashlight resting on a stool that was moved from a different spot in our backyard. It was just resting there and I got closer, I took a look through my sliding glass door and then I just saw the light turn off and I heard footsteps running away," Cuce said.
Other students have experienced similar incidents.
"Across the street, a few nights ago, someone had climbed on top of the roof and was looking through the window of the second floor of these houses," said Cassie Cunningham, Cal Poly student.
The San Luis Obispo Police Department says they've recently increased enforcement in the area.
"We've increased patrol. Every time we get reports of this in the neighborhoods, we do try and spend the free time we have in the neighborhoods trying to contact anybody that looks suspicious," said Lieutenant Fred Mickel, San Luis Obispo Police Department.
Lieutenant Mickel encourages everyone to lock their doors and close their blinds or curtains to prevent anyone from seeing inside.
He also says that if you do see or hear anything suspicious, call police right away so officers can respond to the scene and investigate.
San Luis Obispo police did arrest a man this past Saturday after he was found looking through a bedroom window at 12:30 in the morning.
He was arrested for prowling, peeping, and resisting arrest.
