PHILADELPHIA (AP) — Officials are investigating what caused a gas leak that led to the explosion of a Philadelphia row house, injuring eight people.
Inspectors spent several hours at the scene of Monday's explosion and concluded that a gas leak was to blame for leveling the unoccupied home in south Philadelphia that was being remodeled. Investigators are expected to return to the scene Tuesday as they try to figure out what caused the leak.
One person remains in critical condition with burns. Seven others were treated for minor injuries.
The Fire Marshal, the Department of Licenses & Inspections and Philadelphia Gas Works are investigating. PGW has shut off service to the block.
The explosion comes less than two months after a collapse that killed six people at a downtown demolition site.
