UPDATED 4:46 p.m. Dec. 15, 2010:
KSDK is reporting that the fire was in an unoccupied, one-story, brick warehouse near Gratiot and Theresa.
They also report that a cutting torch, perhaps being used for workers to ready the space for a new occupant, is to blame for the blaze.
A large fire has been reported near the Steelcoate building near Chouteau Ave. and Grand Blvd. We'll keep you updated as we confirm more about this story.
If you can confirm the fire's location or send us more photos of the fire (from a safe distance!) send them to email@example.com or Tweet @stlpublicradio.
