Bensalem police were alerted to the post by an anonymous tipster on April 18, the department said in a release. Officers notified school administrators, who issued a shelter-in-place order "out of an abundance of caution," police wrote.
The order was later lifted with no interruptions to school activities, they added.
Investigators said they "quickly identified" the author of the post as 30-year-old Christian DeFlorio, a former student at Holy Ghost. DeFlorio is thought to be in Miami, Florida, and is "not a direct threat to students at this time," police said.
DeFlorio is wanted on an arrest warrant for terroristic threats and related charges, Bensalem PD wrote.
