Fire officials say two fires that sparked within hours of each other in Southbridge, Massachusetts, are not connected.
The first fire sparked near Main and Central Streets Sunday afternoon.
A few hours later another blaze started at a home on Benefit Street.
The second fire displaced 8-to-10 families, but was quickly put out.
The first fire, however, was an hours-long battle for firefighters that reached six alarms.
The building housed more than half-a-dozen businesses and the top two floors served as a rooming house.
Crews said the nature of the building made it difficult to put out flames.
One firefighter was taken to a hospital, but he's expected to be alright.
Authorities believe the first fire is suspicious, but at this point, there's no word on a cause just yet.
Officials believe the first fire may have been arson, but the cause of both fires remain under investigation.
