NORTH FORT MYERS, Fla. - An early morning house fire in North Fort Myers is being called arson and is now under investigation.  The State Fire Marshal has been called in to the home on the corner of Rich Road and Leetana Road.

Bayshore Fire Department responded to a report of a fire at the home just after 2:30 Wednesday morning.  The vacant, two-story house was fully engulfed with flames when firefighters arrived on scene.  Firefighters say the home had been vacant for more than a year.

It took firefighters about 45 minutes to stop the fire.  The fire chief on scene says water supply is an issue on rural fires like these.  He requested help from North Fort Myers Fire and Cape Coral Fire to help.  No one was injured, but one firefighter has been treated for heat exhaustion.  He has since returned to duty.

Lee County Sheriff's deputies and fire investigators did question a man who was on the scene, but at this point do not have a suspect.  Fire investigators will begin to search for a cause of the fire once firefighters say the scene is safe enough.  A gas can was found near the house and is considered evidence at this time.
