Chopper 6 over Penn State Abington's campus as police investigate a potential threat
Mohammad Alatmah was being held on a $50,000 bond and is charged with terroristic threats, harassment and disorderly conduct, police said. He is a student at the school.
Just before 10 a.m. Wednesday, Penn State Abington closed and asked anyone on campus to shelter in place inside a building.
At the time, PSU Abington suspended classes and told students to not come to campus.
The all-clear was given around 11:10 a.m.
Alatmah is scheduled for a preliminary court hearing on November 4.
