A spokesperson for the community college says a text alert was sent out notifying students of the incident, and ordering those on campus to shelter in place.
Masterman High School, located just across the street from the college, has also been placed on lockdown as a precaution.
This comes just one day after an online post threatened an attack at a college or university in the Philadelphia area. There is no indication, however, that the incidents are connected.
And it was last May when the Community College of Philadelphia was last placed on lockdown after a student flashed a weapon during a dispute in a chemistry class.
