University of New Hampshire police said they are investigating a series of alleged druggings and sexual assaults.
Police were initially investigating two incidents and received a report of a third case Wednesday.
A person of interest has been identified, and police say all three incidents took place on campus.
One case occurred sometime between 10:30 p.m. Friday and 3 a.m. Saturday in the suspect's residence hall on the UNH campus in Durham.
"The impacted party described possibly having their drink drugged during the incident," police said. "The suspect and impacted party were known to each other."
UNH police said they received a second report on Monday from another person who said the same suspect might have drugged them as well on Thursday night.
"It's very unfortunate and concerning," said student Ava Vieira.
She and other students received an alarming email notifying them about the incidents.
"Me and my roommates had just been talking this weekend about how we feel so safe on this campus, too. But after reading that, it's like, well, maybe it's not as safe as we thought," Vieira said.
The incidents are being investigated by the UNH Police Department and other administrative offices on campus. Anyone who feels unsafe on campus is encouraged to call UNH police at 603-862-1212 for a safety escort or other assistance.
