WESTPORT — A Westport man is facing drunken driving charges after he allegedly fell asleep at the wheel and crashed into a guardrail.

Police responded to reports of a car crash near Nyala Farms around 12:30 a.m. Friday morning.

On the scene, police found a Mercedes-Benz stuck on a guardrail in the northbound lane with its driver standing outside the car.

The driver of the vehicle, Enyinnia Ugorji-Ufomaduh, told police that he fell asleep at the wheel and crashed the car into the guardrail.

In talking with Ugorji-Ufomaduh, police said they noticed his eyes were “glossy and bloodshot” and that he smelled strongly of alcohol. Police said the driver eventually admitted to drinking alcohol prior to the accident.

When Ugorji-Ufomaduh failed the field sobriety test, police took the 28-year-old into custody. At headquarters, a breath analysis test showed him to be above the legal blood alcohol limit, police said.

Ugorji-Ufomaduh was charged with operating a vehicle under the influence of alcohol and failure to drive in the proper lane. He was released on a $500 bond, and he is scheduled to appear in court on Aug. 16.
