MARIETTA, Okla. -- Marietta Police Chief William Baker remains on suspension pending an internal investigation by city leaders. Now, his police department has moved to a new location. We’re told Monday that it may be due to evidence that was being stored in the police station seized in a traffic stop over a month ago in which Baker failed to properly dispose of ingredients used to make methamphetamine.

Chief Baker was put on leave over a week ago. A source told KXII-TV on Monday the same reason for his suspension may have caused the city to close the police department and move it to Main Street.

While no one from the City of Marietta would go on the record on Monday, we're told that Chief Baker failed to properly dispose of ingredients used to make methamphetamine.

The ingredients were evidence, and were apparently left in the police department for weeks.

The noxious fumes caused several city employees including other officers to become ill.

Meth ingredients can include ether, Freon, and ephedrine, but it's not clear which chemicals were being stored at the police department.

We're told the ingredients were from seized in a traffic stop over a month ago.

The Marietta mayor would not confirm or deny the accusations but did say the department had been moved for the time being, and the investigation will continue.
