A Massachusetts State Police trooper is out of a job for allegedly hurling racial slurs during an off-duty confrontation with a driver, department officials said.

The rookie trooper, who was not identified, was fired Tuesday for “unacceptable conduct” over an encounter with a motorist last weekend in Revere, department officials said in a statement.

The incident — which allegedly included the use of racial slurs — took place on Revere Beach Boulevard, state police said. The race of neither the trooper nor the driver involved was disclosed by authorities.

“I am disgusted and disappointed by the conduct that occurred, which is the antithesis of the standards of conduct and personal behavior we expect and demand of our members,” Col. Christopher Mason said in a statement. “This subject is not fit to wear the badge or call themselves a member of the department.”

The trooper, who graduated from his recruiting class in May, had been assigned to the Danvers barracks and was still in his one-year probationary period, Mason said.

State police also referred the matter to Attorney General Maura Healy for a review of any potential civil or criminal action, department officials said.

The trooper learned of his firing Tuesday afternoon and turned over all of his department equipment, state police said.

“No further information is being released at this time,” Tuesday’s statement concluded.
