Retired Air Force Maj. Gen. Richard V. Secord, convicted last month of drunk driving in Fairfax County, was charged with the same offense this week in Vienna, officials said yesterday. Secord, a figure in the Iran-contra affair, was arrested about 1:45 a.m. Wednesday after an officer decided to investigate a suspicious vehicle heading west on Route 123, a spokeswoman for the town said yesterday. "The vehicle began to move very slowly and almost came to a complete stop in the intersection when the light was green," said Marie Kisner, the town's public information officer. Secord was arrested at Flint Hill Road and taken to the Fairfax County jail, where he appeared before a magistrate and was released several hours later on a $750 cash bond, Kisner said. In addition to drunk driving, Secord was cited for refusing to give a breath or blood sample, she said. Conviction on the civil complaint could mean revocation of a license. On May 11, Secord was convicted in Fairfax General District Court of driving with an alcohol level of 0.20, twice the legal amount to be considered intoxicated while driving in Virginia. District Judge Barbara L. Kimble sentenced Secord to 30 days in jail, suspended his driver's license for six months, imposed a $500 fine and ordered him to enroll in the county's Alcohol Safety Awareness Program. She then suspended the jail time and $200 of the fine and allowed Secord to drive his car to work and to the alcohol program. The maximum penalty for the misdemeanor charge is up to one year in jail, a $1,000 fine and loss of a driver's license for six months. Secord, 56, filed an appeal and a new trial was scheduled for Aug. 24. Of Wednesday's charge, Secord's attorney, Steven M. Garver, said, "I hope and would expect that the charge would ultimately be dismissed." Secord, who lives in the 1100 block of Arbor Glen Way in Reston, was the chief operative for former National Security Council aide Oliver L. North in supplying munitions to the Nicaraguan contras and selling arms to Iran. The retired general faces trial on numerous charges, including allegations that he perjured himself during the congressional probe of the affair.
