False reports of active shooters at Villanova University and the University of Tennessee at Chattanooga on Thursday led to panic and temporary lockdowns at the two campuses as they kicked off their fall semesters.

In Pennsylvania someone called 911 at about 4:30 p.m. EDT (2030GMT) reporting a shooter in a Villanova law school building with at least one wounded victim. Students received texts from the school's alert system saying “ACTIVE SHOOTER on VU campus. Move to secure location. Lock/barricade doors.”

The school's president later said it was a hoax.

After multiple law enforcement agencies including the FBI responded alongside local fire and emergency crews, the lockdown was lifted less than an hour later. School officials said there was no evidence of any threat.

The initial report sent police scouring the campus and even had some law enforcement officials suggesting they believed there was a shooter.

Villanova is a private Catholic university in the Philadelphia suburbs. It borders Lower Merion Township and Radnor Township at the center of the city’s wealthy Main Line neighborhoods.

The Augustinian school got extra attention this year as the alma mater of new Pope Leo XIV.
