CEDAR RAPIDS, Iowa (AP) — Authorities say two men have been arrested after the remnants of a methamphetamine lab were found inside a Taco Bell in eastern Iowa.

The Cedar Rapids Police Department says officers found two men outside the restaurant early Tuesday. One identified himself as a Taco Bell employee.

Officers entered the closed restaurant and found meth lab remnants in a utility area.

The men were identified as 31-year-old Christopher Adam Matous and 56-year-old Kent Jerome Duby. They were arrested and charged with conspiracy to manufacture methamphetamine. Matous faces additional charges including meth possession. Court records do not list attorneys who could comment for the men.

Taco Bell says in a statement that one of the men was an employee who's now fired. They say the restaurant will be sanitized before it reopens.
