A Petaluma man with prior drunken driving convictions was arrested Monday after officers saw him drive away from a local bar.

Steven Mark Roetter, 40, was prohibited from being at bars and driving with any alcohol in his system according to the terms of his probation for two prior DUI convictions, Petaluma Police Sgt. Ken Savano said.

However at about 4:45 p.m. Monday an officer saw his gray 1999 Ford Ranger pickup outside a downtown bar, Savano said. The officer waited to see if Roetter was violating his probation as part of the city's Habitual DUI Offender Stakeout Program.

About 15 minutes later, Roetter exited the bar and drove away, Savano said. The officer pulled Roetter over on English Street near Hill Boulevard and towed his pickup, which was impounded for 15 days.

A test later found that Roetter's blood-alcohol content was 0.11 percent, Savano said.

Roetter was held on $45,000 bail on suspicion of drunken driving with two prior convictions and violating the terms of his probation, jail staff said.
