A ringing cell phone lying in the middle of the road, an empty car parked on an embankment, its windows down and engine running and a man yelling in front of a Round Hill Road home led to the arrest early Tuesday of Edwin Lugo, 38, of Bridgeport, on a drunken-driving charge.

Police responding to a complaint from a Round Hill Road resident about a man yelling in the street about 12:30 a.m. found a Mercedes on Elm Street, partially parked on an embankment. The car's engine was running, the gear shift was in reverse, police said, and the vehicle was facing in the wrong direction. The car's windows were rolled down despite the rain, and no one was in or near it.

Officers found a cell phone lying on the surface of Noyes Road. The phone was ringing, and an officer answered it. On the other end was Lugo's girlfriend, who said Lugo had her car, according to the report.

Lugo was shortly found on Round Hill Road -- yelling, police said -- and told police he was on his way to Norwalk from Mohegan Sun casino, according to the report.

Police said he admitted to smoking marijuana and drinking. He had an odor of alcohol on his breath, police said, and failed field sobriety tests.

Lugo, a resident of Calhoun Place, Bridgeport, was charged with driving under the influence and released on a $100 cash bond. He is scheduled to appear Jan. 28 in Bridgeport Superior Court.
