Officer Michael Labrozzi of the Sag Harbor Village police had just started an overnight shift Saturday when he saw a 2014 Ford Explorer backing out of a parking spot on Main Street, crossing the double yellow line into the oncoming lane, then moving south, with headlights off. It was a little before midnight. He stopped the car and asked the driver, Brooke L. Sweetser of Hampton Bays, 47, to perform roadside sobriety tests. She reportedly failed, and was taken to headquarters, where her breath test produced a reading of .15, according to the report. She was placed in a holding cell to await a morning arraignment. Six hours later, again on Main Street, where the speed limit is 20 miles per hour, the same officer clocked a 2014 Porsche Boxster at 50 m.p.h. As the car approached the fork between Main and Madison Streets it swerved, almost striking a “No U-Turn” sign, he reported. The driver, Christian V. Greco, 24, was taken to headquarters, where his blood-alcohol test reportedly produced the same .15 reading. A few hours later, the two drivers were taken across a catwalk that connects police headquarters with the village courthouse, to be arraigned on the misdemeanor charges before Justice Lisa R. Rana. Ms. Sweetser was represented by Edward R. Burke Jr., who told the court that his client worked at two separate businesses. He requested that she be given a hardship license, which was granted. The temporary license allows its holder to commute from home and work at specified times. Mr. Burke acted as Mr. Greco’s attorney as well. Mr. Greco, a lifelong resident of Southampton, told Justice Rana he was working as an intern in the Suffolk District Attorney’s Major Crimes Bureau. Both defendants were released without bail, but with a future date on the Sag Harbor criminal calendar. East Hampton Village police arrested Anthony Drupe White, 34, early Friday morning. The Bridgehampton man was behind the wheel of a 2001 Chevrolet Impala, headed east on Pantigo Road, when, police said, he began swerving. He was pulled over across from East Hampton Town Justice Court. “I was going to meet a friend at the Stephen Talkhouse,” he told the arresting officer. His breath test at headquarters produced a reported reading of .14. Because Mr. White has a prior conviction for driving while intoxicated, his car was seized, as required by county law. The conviction apparently happened over 10 years ago, since he was charged with a misdemeanor rather than a felony. He was released after posting $250 bail. East Hampton Town police did not report any alcohol-related arrests over the weekend, an unusual occurrence during the summer months.
