A traffic stop in Sag Harbor on the afternoon of Easter Sunday led to the arrest of a Springs man, Ervin A. Chavez-Felipe, 42, on a felony charge of aggravated drunken driving.Police said they pulled him over after his 1997 Chevrolet went through a stop sign on Madison Street, and that he failed roadside sobriety tests. Back at headquarters, his breath test produced a reported reading of .18.Mr. Chavez-Felipe, whose previous conviction for driving while intoxicated has automatically raised this charge to the felony level, was arraigned Monday in Sag Harbor Justice Court before Associate Justice Janine Rayano. Noting that there is a county court warrant against him for failure to pay a fine, she set bail at $1,500. He could not pay it and was sent to the county jail in Riverside, where he remained as of yesterday.An East Hampton woman narrowly missed being charged at the aggravatedmisdemeanor D.W.I. level after her arrest on Friday night. Tracey L. Schenck’s breath test registered at .17 at East Hampton Town police headquarters in Wainscott, according to the report. Ms. Schenck, 28, driving a 2010 Ford with Alabama plates, was stopped on Bluff Road in Amagansett for failing to signal a turn from Indian Wells Highway, police said.She has no prior brushes with the law, her attorney, Edward Burke Jr., pointed out at her arraignment on Saturday morning, as he asked Justice Steven Tekulsky to release her without bail. Justice Tekulsky agreed.Mr. Burke made the same argument that morning for Miguel J. Araiz, 56, whose 2017 BMW had been stopped on Route 114 in East Hampton the night before for swerving across the double yellow lines, according to police. His breath test produced a reading of .12. Justice Tekulsky ordered Mr. Araiz, who splits his time between East Hampton and Manhattan, to be freed without bail.Mr. Araiz has never been in trouble before with local law authorities. He was, however, charged by the Securities and Exchange Commission in 2013 for a series of irregularities dating back several years. The S.E.C. said he had twice made loans to Further Lane Assets Management, of which he is sole owner, from hedge funds he controls, without informing the funds’ investors. He paid a personal fine of $150,000, in addition to another $350,000 paid by the Further Lane firm and another company he controlled.
