An SUV crashed into a Post Road East office building early Thursday, briefly entrapping the driver, who police said was driving drunk.

The crash also destabilized a nearby utility pole and wires, posing a safety hazard to passing traffic.

The incident took place about 12:30 a.m. Thursday, when a white Ford Explorer left the road and smashed into a corner of the building at 468 Post Road E., across the street from Fire Department headquarters.

Firefighters dispatched to the scene found the vehicle's airbag was triggered by the crash impact and the driver was still inside.

The driver -- identified as George Arias, 53, of Bridgeport -- suffered minor injuries, firefighters said, and was quickly removed from the SUV.

Arias was charged with driving under the influence and failure to drive in the established lane, police said. After posting $500 bond, he was assigned a July 12 date in Norwalk Superior Court.

The Explorer's front end, which protruded into a first-floor office, smashed exterior siding, shattered a window and caused interior damage.

When the SUV left the road, firefighters said the vehicle severed a guy wire that helped to stabilize a nearby utility police, causing the pole and some wires to lean toward the roadway and pose a hazard to traffic.

The town's Building Department dispatched an official to secure the damaged structure, which was sealed with a tarp until permanent repairs are made.

A crew from Connecticut Light & Power was called to the scene to stabilize the utility pole and wires.
