NORWALK - Norwalk firefighters are investigating after they spent last night battling two separate fires.

The first one happened on Cannon Street around 5:30 p.m.

They say the fire took a long time to battle because the house was filled with garbage.

Just as firefighters were wrapping up, they got another call to a home on Larsen Street.

That fire left 15 people homeless.

Officials say one person suffered minor injuries and a firefighter was taken to the hospital for dehydration.  They say that firefighter was back at work today.
