A suspect is in custody after reports of a person with a weapon put the Community College of Philadelphia on lockdown on Tuesday morning, police said.
No shots were fired and there were no reports of any injuries, said Tanya Little, a spokeswoman for the Philadelphia Police Department.
Police made a sweep of all campus buildings as they continued to search for a gun while the entire campus remained under lockdown.
The FBI had warned colleges and universities on Sunday about a recent social media post threatening violence on Monday at a Philadelphia college or university.
The FBI said other parts of the country faced similar social media threats after the mass shooting that left 10 people dead at a community college in Oregon on Thursday.
Philadelphia Police Commissioner Charles Ramsey told reporters that Tuesday’s incident didn’t seem to be related to Monday’s threat or to the Oregon shooting.
