A house fire in Sharon is now under investigation following a multi-agency response to the blaze early Sunday morning. 

The fire, initially called in around 2am on Sunday, fully engulfed the Florence St. home by the time firefighters arrived. 

It took several hours for firefighters to control the blaze, which reignited several times. Sharon Fire Department says that nobody was inside the home at the time of the fire. 

It is currently unknown what caused the blaze, but officials say fire investigators will return to the scene once it's certain that the home won't reignite.
