Burlington Police are warning residents about a series of disturbing incidents in the city's Hill Section.

It started July 26, when a woman walking late at night reported a man exposing himself and grabbing her chest on College Street. He was described as a white man in his late teens or early 20s, thin, with long hair.

Then, Tuesday night, a woman reported a man looking through her window as she was changing on Loomis Street. He was a white man with short, dirty blond hair, a large forehead and dark eyes.

And just before 1 a.m. Friday, a woman reported seeing a man naked from the waist down touching himself on College Street near South Willard Street. Police say he is described as a white man of average build.

"These types of complaints kind of come and go. It's always a little more concerning to us when we have grouped together in a specific area with descriptions that may be similar. It becomes concerning to us that there is one person that is either doing this type of thing or if there is more than one person doing it in the area," said Det. Morgan Lawton of the Chittenden Unit for Special Investigations.

If you know anything that would help police in their investigation, they want to hear from you. Call 802-652-6800.
