KALAMAZOO (WKZO) -- A fire broke out at Graphic Packaging in the 1500-block of North Pitcher around 6:30 a.m. Wednesday.

A fire sparked by a machine on the ground floor was quickly doused by a sprinkler system, but Kalamazoo Public Safety had to battle the blaze as it spread to the roof of a building.  They had help from the Kalamazoo Township Fire Department for several hours as they made sure the fire hadn't spread any farther.

No one was injured and investigators are still looking into the specific cause of the blaze.
