An evacuation was ordered throughout Mercy College ? located in Manhattan, New York ? late Wednesday night over an alleged bomb threat, the institution's social media accounts and local reports indicated.

The school's officials received "an unsubstantiated letter with the [bomb] threat", NBC New York said citing the local police department.

In an "emergency update", the College through its Twitter account advised students and any other person present in or around Manhattan campus ? on West 35th Street, near Penn Station ? to leave the premises and that "the building is closed until further notice".

As of now, authorities and college officials "are continuing to monitor the situation", one of the tweets said.

In addition, evening classes at Mercy College have also been cancelled.

When Geo.tv reached out to Mercy College for further information, Catherine Cioffi, J.D. ? the director of public & community relations and marketing at Mercy College ? reiterated that evacuation is still in order and all classes for the evening have been cancelled.

"I cannot reveal any more or anything regarding the threat [level] right now, but police are still on the scene," Cioffi said.

On the other hand, Midtown Precinct South ? the closest to Mercy College ? declined to comment on the matter when Geo.tv reached out to them over the phone.
