Anthony D. Romero, the director of the American Civil Liberties Union, was arrested on a charge of driving while intoxicated in June, said on Tuesday.

Romero, who is 45 and has a house in the Dune Alpin section of East Hampton, was driving a 2005 Mini Cooper erratically -- yet very slow -- into the village on June 26, according to the police report.
