Police say they arrested 57-year-old Michael Sheehan of Arlington late Friday night after he was spotted driving erratically in the rear parking lot of the police station, reserved exclusively for police vehicles.

Sheehan is scheduled to be arraigned Monday in Barnstable District Court on charges of operating under the influence and trespassing.

An officer spotted Sheehan and at first thought he was a colleague arriving for the midnight shift. But after noticing he was driving around aimlessly, stopped him.
