More than a dozen people have been left homeless after fire swept through an Oswego apartment building on Wednesay afternoon.

The fire erupted at 80 East Mohawk Street at about 1:40 in the afternoon, and it's believed that smoke detectors in the building alerted everyone quickly and there were no injuries reported. There are six units in the building.

The fire originated in an apartment on the second floor and the tenant there wasn't home at the time, so the fire had a head start.

Residents of the building evacuated after the alarms went off and the fire department was on scene within minutes, but the apartment where the fire started was gutted, and the other units suffered smoke and water damage, and the fire chief says the building is now uninhabitable, for the time being.

The Red Cross is now assisting tenants with temporary shelter as the fire department investigates the cause of the fire.

Fire Chief Jeff McCrobie says "Crews did a great job in knocking this thing down in what appears to have been an unoccupied apartment at the time. The fact that there were working smoke detectors is very much worth noting."
