PHILADELPHIA (TheBlaze/AP) -- Police say a man reportedly pulled a gun during a confrontation with another man outside a Community College of Philadelphia building, prompting a campus lockdown and a large police response.
Police Commissioner Charles Ramsey told reporters Tuesday that there were no reports of shooting or injuries.
CBS Philly reported that police arrested a suspect amid the campus lockdown:
Ramsey says the encounter was not random but rather "two individuals who have a history." He says the person who reported having a gun pulled on him around 9:30 a.m. was a student, but it's unclear whether the other man was a student.
Students and staff were asked to shelter in place while police searched the campus. Nearby public schools also were placed on lockdown.
On Monday, Philadelphia-area colleges and universities increased security amid an FBI warning about an online posting threatening violence.
