VILLANOVA, Pa.- Villanova University was locked down for several hours after a gunman fired shots at police and escaped early Wednesday, authorities said.
No injuries were reported.
Police searched the campus in the affluent Philadelphia suburb with infrared cameras, police dogs and a state helicopter but failed to locate the shooter, authorities said.
Police had received reports of a man acting suspiciously and he opened fire as officers approached him for questioning about 4:30 a.m., authorities said.
Villanova classes resumed at 11:30 a.m. Other schools in the area also opened several hours late or closed for the day because of the search.
