Firefighters said a burning candle started a fire Tuesday morning at an apartment building in the Oviedo area of unincorporated Seminole County.

The Seminole County Fire Department said the fire broke out around 2:09 a.m. in a first floor unit of the three-story building.

When firefighters arrived, an audible alarm was going off, and residents had evacuated their apartments safely.

Once inside, firefighters determined the sprinkler system stopped the fire.

The American Red Cross is providing assistance to one occupant.
