The University of Massachusetts Police Department is investigating several reports of a male looking at female residents of John Adams Hall while they have been showering, according to a crime alert sent out to the campus community Saturday night.

According to the alert, UMPD received four reports of similar incidents, with the first occurring in September.

The reports allege a white male has been seen looking or attempting to look under showers on the third and sixth floor bathrooms of the residential hall. Two women reported seeing a black iPhone under the partition, which they believe to have taken pictures or video.

According to the alert, one report described the male as college-aged with dark hair, a backwards baseball cap, gray T-shirt, teal shorts and teal Sperry boat shoes. Another described the male as lying on the ground and wearing a blue checkered shirt and blue jeans.

UMPD encourages residents to report any suspicious behavior to the police. UMPD can be reached at 413-545-2121 or at http://www.umass.edu/umpd/anonymous-witness-form.
