DETROIT (AP) -- Police say three Chrysler workers were arrested after the automaker tipped authorities that they may have been using illegal drugs while on break.
The Detroit News reports the workers at Detroit's Jefferson North plant were arrested Jan. 24 and haven't yet been formally charged.
Last year, Chrysler fired 13 plant workers caught by a Detroit TV station drinking alcohol and smoking what appeared to be marijuana during breaks at the same plant.
The plant produces the Jeep Grand Cherokee and Dodge Durango sport utility vehicles.
Chrysler confirmed Friday that it was cooperating with police. The automaker says in a statement that the "safety and security of all Chrysler Group employees is our first priority."
