DETROIT – A Detroit police officer attended a Michigan State Police training class with alcohol in his system, officials confirm.

WXYZ-TV (Channel 7) reported that the training took place Thursday, and Detroit Police Chief told the TV station that an internal investigation would be conducted.

“The bottom line is that he showed up to work under the influence of alcohol,” Craig told the television station. “This was a Michigan State Police training, he blew a .08. Certainly that’s a problem, it’s a problem for me, and it may be a problem on how it was handled after that.”

The officer was not disciplined by state police at the event.

State police Lt. Mike Shaw told the Detroit Free Press the officer was attending a DataMaster training class. A DataMaster is an instrument used to analyze blood alcohol concentration via a breath sample.

"During that class he volunteered to give a sample and it was determined he had alcohol in his system. The MSP sergeant dismissed him from the class and sent him to his department. His command staff was notified. He does not work for us so we can not discipline him. That will be up to his employer."

A Detroit police spokesperson confirmed Saturday morning that an internal investigation is underway, but did not share more information about the officer or the incident.
