NORTH CHARLESTON (WCSC) - Investigators are searching for clues as to what caused an early morning fire at a home located at the corner of Rock Street and Ashley Phosphate.

Fire department spokeswoman Bianca Sancic said fire crews responded to the scene just before 3:30 a.m.  First arriving units reported smoke and flames showing from the two-story wood frame residence at 7408 Rock Street.

Officials say the fire started on the front porch of the vacant home, where a number of chairs and couches were located. From there, the fire moved up the wall, and through the roof.

Responding crews had to shut down a section of Ashley Phosphate in order to battle the blaze. The road was reopened around 8:15 a.m.

This is not the first time the property has been damaged by a fire. Officials say the residence caught fire back in December, and it was never repaired.

There was one report of smoke inhalation by a neighbor.  That person was treated at the scene by EMS.  One firefighter was also treated for a minor ankle injury and released.

An arson investigator is currently looking at evidence from the scene.
