Mattapoisett Police Chief Mary Lyons was arrested on an OUI liquor charge late Saturday night in Bourne, according to Massachusetts State Police.
The 61-year-old Lyons was also cited for a marked lanes violation.
At around 11 p.m. Saturday, state police say a trooper pulled over Lyons after she was allegedly driving a 2014 Lexus erratically on Route 28 north in Bourne.
The officer approached the vehicle and “made observations of the operator”.
After giving Lyons a field sobriety test, the trooper determined that she was intoxicated. She was booked at the Bourne barracks.
A bail clerk released Lyons on “personal recognizance”, according to State Police Director of Media Communications Dave Procopio.
She is pending arraignment in Falmouth District Court.
