Three separate incidents involving possible explosive devices at Temple University and the University of Pennsylvania put students on edge Sunday night.
A hotel on Temple University's campus in North Philadelphia was evacuated after Temple Police discovered a suspicious device near the intersection of Broad and Berks streets around 5:30 p.m.
The incident caused school officials to evacuate the Conwell Inn, which is located along Liacouras Walk on Temple's campus in North Philly.
The Philadelphia police bomb disposal unit responded and determined it was a non-functioning device.
An investigation revealed the suspicious device was a movie prop left behind by another university's students who were filming near campus last week, according to a Temple spokesman.
An alert was sent out to Temple's staff and students just before 5:55 p.m. informing them of the evacuation and warning them to avoid the area.
About 10 minutes later, a second alert was sent out telling the Temple community that the area has been reopened and that the "Philadelphia Police Department Bomb Squad have taken the suspicious device from campus."
