DELAWARE TOWNSHIP - An overnight fire ripped through a historic inn in Hunterdon County.

Firefighters found smoke coming from The Sergeantsville Inn in Delaware Township early Monday. But flames eventually tore through the roof of the two-story stone structure that is more than 300 years old.

Firefighters from several nearby communities, including some from Pennsylvania, were called in to help extinguish the fire.

Fire officials say one firefighter sustained a minor knee injury. The cause of the fire remains under investigation, however the Hunterdon County Prosecutor's Office does not believe it is suspicious.
