A Riesel police officer resigned Tuesday after coming to work with alcohol on his breath.
Former officer James Black had been with the department for less than a month.
Black was given a breathalyzer test, but the results have not been released.
The Riesel police chief say he should have known better.
Riesel is down to two officers on duty.
