Officers went to the fast-food restaurant, 2621 Blairs Ferry Road NE, at 4:42 a.m. to check out a suspicious person report, said Cedar Rapids public safety spokesman Greg Buelow.

The Taco Bell was closed at the time, but officers encountered two men outside, one who said he worked there.

Police then called the restaurant’s manager to the scene and went with him inside to check it out, Buelow said.

Officers found remnants of a meth lab in a utility area, he said. But it was unclear if meth had actually been cooked in the restaurant.
