Investigators said a man in his 60s arrived at the Harbison Avenue and Levick Street building, which houses the 2nd and 15th police districts, around 4:40 p.m. Sunday and handed over a plastic-wrapped grenade he said he discovered inside a radio he purchased earlier in the day at a flea market, the Philadelphia Daily News reported Monday.
"Once they discovered it was a grenade, safety became paramount and we wanted everyone out of the building," Sgt. Leo Costello said.
Costello said the bomb squad was called to dispose of the grenade, which was found to be live, and the scene was cleared by 5 p.m.
