A Virginia lawyer has sued Arlington County officials, charging that she was unconstitutionally jailed, forced to undress and searched after being arrested on a drunk-driving charge a year ago.

Lucy N. Logan asserted in the law-suit that she was illegally detained because of her sex and because county officials knew she practiced law in Arlington. The suit, filed in U.S. District Court in Alexandria, seeks $250,000 in damages.

Arlington Sheriff James A. Gondles said in an interview that motorists arrested in Arlington on drunk-driving charges are frequently ordered detained until they are sober. Until jail procedures, he said, they must be stripped and searched to check for weapons and other illegal possessions.

Norris Shealy, Arlington's chief special magistrate, declined to comment yesterday. Shealy and Gondles were among 11 Arlington officials sued by Logan.

Logan said in the lawsuit that she was arrested on March 6, 1976, by Arlington police on charges of driving while intoxicated test. She was later acquitted on both charges in General District Court, she said.

After her arrest, Logan alleged, she was ordered jailed for about four hours. She said she was taken to a jail cell and forced to remove her clothing and "to submit to a visual strip and body cavity search."

"The windows of the cell . . . were only partially covered by blinds, which were in a state of disrepair, and the cell was monitored by a closed-circuit television camera, thus exposing [Logan] to public view," Logan's lawyer, Thomas A. Guidoboni, said in the suit.

Logan also charged that she was unconstitutionally prevented from contacting an attorney to represent her despite her "repeated requests." She said her arrest took place about 7:45 p.m., but she was not allowed to call a lawyer until about 10:15 p.m.

Logan contended that the actions by Arlington officials violated constitutional protections against unreasonable seizure, excessive bail and cruel and unusual punishment and unconstitutionally denied her "due process."
