HOUSTON -

Houston firefighters said a candle was to blame for an apartment fire in northwest Houston.

Fire crews rushed to the Willow Green Apartments on Willow Place just before 1 a.m. Wednesday.

Crews were able to knock out the flames quickly.

Investigators said a candle left burning started the blaze when a small patch of carpet caught fire and then spread to a wall.

No one was injured in the fire.
