Firefighter injured while investigating underground electrical issue at Dunkin' in Camden County

CAMDEN, New Jersey (WPVI) -- A Camden County firefighter was injured on Sunday while investigating an incident involving an underground electrical issue by a Dunkin'.

Officials in Camden said one firefighter sustained non-life-threatening injuries when he came in contact with an electrical box at a Dunkin' on the unit block of South Broadway Street.

The firefighter was transported to Cooper University Hospital for his injuries.

Smoke was seen coming from a manhole near the Dunkin' around noon.

Officials say a fire was emanating from the manhole cover of an underground electrical unit below the coffee shop.

According to officials, the underground conduit became energized and caused a power surge. That caused an electrical panel at the Dunkin' to explode.

"There was a minor explosion on the interior that injured the firefighter," commented Jesse Flax, the chief of the Camden Fire Department.

The face plate blew off of that panel, striking the firefighter.

He is expected to be okay, officials say.

"Right now he's under hospital care and he's under stable condition for as much as I can tell you right now," said Flax.

No further information has been released on this incident.

PSE&G is assisting in the investigation.

New Jersey Transit light rail service was impacted by the underground fire. Busses were transporting people around the scene.
