Monmouth University is planning to open the campus late on Tuesday following an earlier lockdown and "emergency," the university announced on social media.
The school said it is planning to open campus at 10 a.m. with classes starting at 11 a.m., but for the time being, residents are still being asked to shelter-in-place.
Around 1:30 a.m. Tuesday, the university posted an alert that "There is an emergency at Monmouth University. A lockdown is in effect. this is not a drill. Please close and lock all doors and await further instructions."
The university in the early morning hours said Monmouth University police, with the help from outside agencies, were checking "various areas on campus" and residence halls.
Shortly after midnight, university police received reports that students and staff had received an e-mail from someone claiming to be armed and hiding on campus "where a dangerous device was also placed," according to the Monmouth County Prosecutor's Office.
