David Nelson, 52, of Norwalk, turned himself in to Westport police Saturday morning on a warrant that stemmed from a September traffic accident. The incident occurred on Compo Road South, when Nelson's vehicle flipped over, police said.

Nelson was charged with operating under the influence of alcohol and failure to drive right after police obtained a search warrant on his medical records and determined his blood-alcohol content was 0.210. The legal limit is 0.08.

A Nov. 16 date at Norwalk Superior Court was set for Nelson, who was given a $2,500 bond.
