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."
Two evacuations also occurred on Penn's campus Sunday.
The first incident happened around 4:15 p.m., when a campus security guard found a suspicious device on a table near 36th and Sansom streets, according to the Daily Pennsylvanian.
Authorities evacuated the Kings Court English House while the bomb squad investigated, quickly determining the device was a car battery.
Everyone was permitted to return to the building shortly after 5:30 p.m., according to reports.
A second bomb scare occurred on Penn's campus around 8:30 p.m. when a threat was called in to a Chipotle located on the 3900 block of Walnut Street.
Officials say they evaucated the Mexican chain restaurant and blocked off part of Walnut Street while they investigated.
Police determined the scene was safe and reopened the area about 20 minutes later.
Detectives will continue to investigate who placed the call.
