An investigation is on-going at the Department of Corrections into the theft of between 100 and 200 state license plate tabs from its Jefferson City facility. Police in Kansas City have arrested two people with 30 stolen tabs. Investigators there believe others are involved and many more tabs taken. Corrections Department Spokesman Tim Kniest says security has been tightened afterthe incident came to light. Kniest says it’s not known whether the tabs were stolen at the warehouse or during shipment to license offices. He says it’s unlikelyinmates who work at the factory or in the warehouse stole the tabs, because they are searched before the leave each day.
