The fire that destroyed a nail salon and damaged several adjacent homes in Paulsboro, N.J. is being investigated as "suspicious."
That's according to authorities who tell NBC10 they are looking at surveillance video from a neighboring home to see if it offers any clues as to what happened.
The fire started around 10 a.m. at the Broad Street Nail Salon on 405 West Broad Street. The flames caused the roof of the building to collapse and eventually spread to other homes attached, causing damage.
"That house was engulfed. I mean, it went up pretty fast," said Mary Antanaitis, a neighbor, whose home was also damaged.
Firefighters were able to bring the flames under control in about an hour. Investigators say at least one person suffered minor injuries.
Paulsboro Police, the Gloucester County Prosecutor's Office and Fire Marshals Office are all helping with the investigation.
