MINNEAPOLIS (AP) -

A fire at a warehouse in northeast Minneapolis is under investigation.

Firefighters arrived at Marshall Concrete about 7:30 a.m. Friday and saw smoke and fire in the top tier of the 30-foot building. A conveyer belt that runs from the ground to the top of the building was also on fire. Firefighters brought the fire under control before it spread to an adjacent lumberyard.

One firefighter suffered a minor injury from a fall and was taken to Hennepin County Medical Center.
