Sag Harbor Village police arrested a Hampton Bays woman late Saturday night on drunken-driving charges after an East Hampton Village police dispatcher relayed a tip from a motorist of an erratic driver on Route 114. An officer spotted the car and reported seeing it swerve across the bike lane, almost striking a concrete barrier. Kaitlin M. Kelly, 25, was taken back to police headquarters on Division Street, where a breath test reportedly produced a reading that was twice the legal limit. She was released Sunday morning after posting $260 bail.There were no arrests for drunken driving or for any other significant misdemeanor or felony charges in East Hampton Town or Village this past week.So far this year, though, arrests are up over last year’s first quarter, as are calls for police assistance. As of April 30, 2014, there were 4,113 calls logged; this year’s number is 4,303, an increase of almost 5 percent. Arrests in last year’s first quarter were recorded at 164. This year, that number is up to 201.From Jan. 1 to Dec. 31, 2014, the total number of calls for assistance appears to have set an all-time record.
