CEDAR RAPIDS, IOWA (AP) -- Cedar Rapids police say a suspicious smell coming from a port-a-potty turned out to be leftovers from an illegal meth lab.

KCRG-TV in Cedar Rapids says police discovered the remnants on Saturday after responding to a call about the smell.

Officials say someone dumped noxious chemicals into the potty.

Police called a lab clean up company to clear up the hazardous materials.

No injuries were reported and no arrests have been made.
