An explosion has rocked a grinding company in southwest suburban McCook.

Thick black smoke poured out of the building Saturday and forced workers to evacuate.

Firefighters did stop the fire before it spread through the building.

There was no official word if anyone was hurt, but a worker said everyone got out safely.

Investigators were checking Sunday into what caused the blast.
