Officials at Bryant College in Smithfield, Rhode Island, say they are investigating after multiple reports of an intruder breaking into student residences.
According to necn affiliate WJAR, five students reported a stranger broke into their residences and groped them as they slept.
These incidents happened at the university's town houses.
Police do not have a description of the victim.
"We have reached out to all students and asked for their assistance in sharing any information that might be helpful in identifying the individual responsible for what we believe to be five instances of entering unlocked residences and inappropriately touching students while they slept. When the students were awakened and confronted the intruder he left," John Saddlemire, Vice President for Student Affairs and Dean of Students, said in a school letter.
