A car flew off Glen Arden Drive and landed on its roof in a stream after careening out of control when its driver suffered what may have been an epileptic seizure Wednesday afternoon.

The 23-year-old driver was unconscious when emergency crews arrived on the scene near Osborne Hill Road just before 4 p.m., but regained consciousness a brief time later.

Officials told the Fairfield Citizen the passenger said the driver may have lost control of the silver Lexus after suffering an epileptic seizure, causing it to veer off the road and overturn into the water.

The vehicle, which had North Carolina license plates, was traveling down Osborne Hill from North Benson Road, when the driver suffered the apparent seizure near the intersection with Glen Arden, it struck a fire hydrant and knocked it off its base.

The car then rammed a utility pole, snapping it at its base and disrupting power to customers in the immediate vicinity.

The car became airborne, hit a bridge abutment and lost one of its wheels as it flipped over on to its roof in the water.

The passenger was able to get out of the wreckage on his own, but the driver had to be extricated by fire and police personnel.

The driver and passenger were transported to St. Vincent's Medical Center in Bridgeport for treatment of what officials said were non-life-threatening injuries.
