BOSTON (AP) — A Boston police officer who's been on paid leave since September and is now charged with taking a police vehicle without authorization has checked into a substance abuse treatment program after being released on personal recognizance.

Patrick Donovan was arraigned Monday after he was taken into custody Friday.

Authorities say the 38-year-old Donovan took the marked police car from Dorchester and drove it to Revere.

His lawyer says his client is a decorated officer and Marine Corps veteran who has suffered injuries on the job. The attorney says Donovan has checked into a treatment program as a condition of his release.

Donovan has been on leave since allegedly placing a stolen license plate and stolen registration sticker on his personal vehicle.
