Six people were driven from their homes, including a man who suffered minor injuries, by an overnight fire at a condo building in Seminole.

The fire started around 3 a.m. in an upstairs bedroom at the Lake Seminole Villas, 9845 Seminole Boulevard, and crews needed about 20 minutes to put it out. The affected unit and four nearby condos sustained fire or smoke damage, authorities said.

The injured man was treated at a hospital.

Investigators are trying to determine how the fire started.
