STAFFORD TOWNSHIP — Stafford Township police Tuesday evening released video of the massive explosion that ripped through a house and injured 15 people this morning.

The video, captured by the in-car camera of a Stafford Township police vehicle, shows calm on Oak Avenue before the house explodes into pieces.

Police along with fire and emergency medical personnel were called to Oak Avenue shortly before 9 a.m. on the report of a gas leak. Workers from New Jersey Natural Gas Co. were on scene when the explosion occurred around 10:30 a.m.

Seven utility workers were injured, including two who were in critical condition. Six firefighters and two EMS personnel suffered minor injuries.

The house, which was empty and under renovation, was completely blown apart. The debris field covered a one-quarter mile area and houses on either side of the home were also significantly damaged, authorities said.
