HOULTON — Maine state police say a 24-year veteran has been cited for operating under the influence and has been placed on administrative leave during an investigation.

Police say Sgt. Julie Bergan was issued a summons after she failed field sobriety and blood-alcohol content tests after reporting to work Thursday at the Houlton barracks.

Lt. Col. Raymond Bessette declined Monday to release her blood-alcohol level to the Bangor Daily News. The legal limit for driving in Maine is 0.08 percent.

Bergan, who’s 54, is on administrative leave pending the outcome of an internal investigation. She couldn’t be reached immediately for comment.
