A Temple University student, armed with a gun, remains barricaded in his North Philadelphia house near campus, police said.
Police were still at the scene as of 9:30 p.m.
Earlier, an officer at the scene had erroneously reported that the student had killed himself.
A police SWAT team descended on the 1800 block of North Willington Street in North Philadelphia about 10:44 a.m., going door-to-door to warn residents of the situation.
The student is believed to be alone.
