BATON ROUGE - Fire and HAZMAT crews are on the scene of a fire at an unoccupied building on Darryl Drive.

Investigators say the fire was started when construction workers were trying to replace metal walls at a building located in the 11000 block of Darryl Drive and a spark from the cutting activity started the fire.

No one was inside of the commercial property at the time of the fire.

A nearby school, St. Louis King of France, was placed on lock down due to the large amounts of smoke as a precautionary measure. School administration says there was no danger to any children during the incident. Darryl Drive was closed as crews worked to put out the blaze.

HAZMAT crews were also on the scene as a precautionary measure.
