Some residents were evacuated from a Southwest Philadelphia apartment complex early Tuesday as police responded to a man armed with a rifle who had barricaded himself inside, police said. Officers were called to the building near 48th Street and Chester Avenue at about 3:45 a.m., Chief Inspector Scott Small said. Police evacuated some residents, but not the entire complex. As of about 5:15 a.m., no shots had been fired, Small said. Investigators were speaking with the man in an effort to resolve the standoff. Police had not provided details about the man or said whether anyone was injured or whether another person was inside the apartment with him. The incident remained ongoing Tuesday morning.
