Evacuations occurred at two different Delaware universities Tuesday, the schools said on social media.

The University of Delaware in Newark said school police were investigating "a report of a potential campus safety incident, and out of an abundance of caution, evacuated Gore Hall, Sharp Lab and Mitchell Hall to prioritize the safety of our University community."

According to an announcement sent out to the school community, University of Delaware police had been notified about a possible explosive device in a campus building Tuesday morning.

Investigators acted fast, evacuating buildings and calling in backup from nearby law enforcement agencies, the university said. The threat, however, was unfounded, according to the school.

"During its investigation, UD Police learned that multiple institutions regionally and nationally received similar reports of potential safety threats," the campus announcement read in part. 

Newark police temporarily closed South College Avenue between Delaware Avenue and Park Place early Tuesday afternoon due to the investigation. The street has since reopened.

Shortly after the street reopened, the university announced that the situation at Gore Hall, Sharp Lab and Mitchell Hall had been resolved and normal activity could resume.

University of Delaware officials urged its community members to continue to call and report any suspicious behavior. 

Josh Robertello, a junior at the University of Delaware, said the threat threw his whole day off.

"It's scary to think about when you hear things like that," he said. "It's pretty terrifying."

In Dover, Delaware State University's academic buildings were evacuated and classes were canceled for the remainder of the day after a bomb threat was received just before 11 a.m.

The university said in a statement on Tuesday afternoon that it worked with local, state and federal authorities to clear buildings on campus in response to the threat. 

All university employees except essential personnel were sent home, and campus is set to reopen on Wednesday.

CBS News Philadelphia has reached out to the FBI for more information about the evacuations, but we've yet to hear back.
