GREENVILLE, PITT COUNTY -

Police said they are investigating a Greenville duplex fire that displaced a family of six as a case of arson.

According to Battalion Chief Shannon Terry of Greenville Fire and Rescue, the fire that erupted at a duplex at 103 Bragg Circle Wednesday afternoon was intentionally set. The fire appeared to have started in a storage room attached to the back of the home, said Sgt. Joe Friday of Greenville Police.

Police did not say if any arrest has been made.

Four kids and two adults were inside Apartment A of the duplex when they reportedly heard a few explosions at about 3:26 p.m. Wednesday, according to fire officials. Those "explosions" were inflated vehicle tires that made loud noises as they burned, said Terry.

The children told their mother and the family of six were able to escape, Terry said. The family in the other duplex unit, Apartment B, were able to evacuate as well.

Fire officials said the blaze started in the back of the building and spread to the attic. Those inside the damaged unit tried to put out the flames, but could not, investigators said.

Apartment A suffered considerable damage and is considered uninhabitable, said Terry. Apartment B had some smoke and water damage, but is still safe to live in.

The Red Cross is helping both families of the damaged duplex.
