MANKATO. (AP) - Drug agents have raided an auto repair shop in Mankato after an employee told authorities that workers were given methamphetamine as bonus pay.

Minnesota River Valley Drug Task Force says an owner of Clear Choice Auto Repair watched as his girlfriend gave a half gram of meth to each employee as a bonus at a company meeting Tuesday night. It wasn't immediately clear how many employees were involved. But, authorities say one of them told law enforcement about the drug bonuses.

Agents say a search of the business turned up syringes and a digital scale that contained meth residue. The owner is being held in the Blue Earth County Jail on a drivers' license violation.
