FAIRLESS HILLS, Pa. (WPVI) --A lockdown was lifted by early afternoon at Conwell-Egan Catholic High School in Fairless Hills, Bucks County after a reported threat.
The lockdown was over by 1 p.m. Tuesday, officials said, and everyone was safe.
Archdiocesan officials say they were informed by law enforcement of an anonymous threat "about a general threat to the safety of the school campus" after the school day had started.
Investigators told Action News the threat warned of a possible shooting. No actual shooting has been reported.
The school was placed on lockdown as a precaution as police conduct sweeps and search the building.
"Archdiocesan high schools take any threat seriously as the safety and well-being of students is always a primary concern," said spokesman Kenneth Gavin.
Some 700 students attend the school.
