Firetrucks remained on the scene overnight, even with the huge flames out. The fire ripped through an abandoned warehouse at 71st and Kingsessing Avenue.

A stubborn situation, the fire wasn’t placed under control until late at night, hours after the 9-1-1 calls first came in at 8:30 p.m.

Fire officials would call for three alarms. The one person hurt, officials say, is a firefighter with minor injuries.

Public records show the warehouse measures more than 60,000 square feet.
