As the face of the Minnesota State Patrol in western Minnesota, Sgt. Jesse Grabow, the public information officer, has been expert as using social media to get people to drive more safely. He often uses the hashtag #SlowDown.

Now Sgt. Grabow is in trouble. He’s been charged with driving 94 mph in a 55 mph zone while on duty, the Forum Communications reports.

“Sgt. Jesse Grabow, a 17-year veteran and valued member of our agency, erred in judgment and broke the law when he was observed speeding on duty without cause,” Col. Matt Langer said in a statement. “We take this very seriously and have initiated an internal affairs investigation now that the city attorney has completed his review.”

The incident on Minnesota 210 happened in April and the State Patrol has not said why it’s taken two months to file speeding charges against Sgt. Grabow.

(Update 1:29 p.m. – A spokesman for the Department of Public Safety says the incident was being reviewed by prosecutors.)
