One person was taken to the hospital with unknown injuries following a fire on the 1700 block of Napoleon Drive in Naperville late Monday, authorities said.

Officials first on the scene reported smoke and fire coming from a second story bedroom in the building.

The fire was quickly extinguished, officials said.

The home was unoccupied, authorities said.
