A series of emails threatening violence against a community college in Pennsylvania led officials to close all five of its campuses for a third day of classes.
Delaware County Community College received about a dozen emails on Thursday threatening “violence against numerous persons”, according to police, who suspect the sender may be a student.
The campuses would remain closed today, college president Jerome Parker said after a meeting between school representatives and law enforcement officials.
College officials hoped to reopen tomorrow.
Officials decided to close all the campuses in part because of the April 16 massacre at Virginia Tech, where a gunman killed 32 people and himself in the deadliest shooting rampage in modern US history.
The college serves about 10,000 students in Delaware County, outside Philadelphia.
