The Fairfax County Police Department has proposed unspecified disciplinary action against the second of two officers allegedly involved in "indiscretions" with two female members of police-sponsored Explorer Scout units during a weekend ski trip. The other officer previously was dismissed.

Police Chief Carroll D. Buracker, who would not describe or characterize the incidents that allegedly occurred on the trip other than as "indiscretions," said the second officer has appealed disciplinary action planned by the department after an internal investigation. The department must respond to that appeal by today, he said.

Other officials familiar with the investigation said the two policeman, who accompanied members of the police-sponsored Law Enforcement Explorer Scouts on a two-day ski trip to Pennsylvania in February, engaged in inappropriate sexual behavior with two girls on the trip. The officials said, however, the behavior did not involve sexual intercourse.

Police have declined to release the officers' names.

Buracker said yesterday the department began an investigation of the events after officials began "picking up rumors from participants" on the trip. "We don't tolerate misconduct on the part of police officers," the chief said. "They have a position of public trust."

Scouts representing the West Springfield and McLean law enforcement posts participated in the trip. Officials said the scouts, ranging in age from 14 to 21, were also accompanied by several other police officers and their spouses, an FBI agent and a Fairfax deputy sheriff.

One of the scout members allegedly involved in the "indiscretions" was over 18 years of age, said Rudolph Flythe, head of the National Capital Area Council of the Boy Scouts of America. Police would not discuss the age of the other member.

Both girls have been removed from the post, police said. National Scout officials said they have taken no action against the two members and that they may be allowed to join other Explorer units.

The police officer who was dismissed last week has filed an appeal of his discharge to the county executive, a Fairfax government spokeswoman said yesterday.

The second officer is appealing the recommendation of the internal police review to Buracker. Under department policy, the chief will decide whether to support, revoke or modify the proposed disciplinary action.

Buracker, who serves as a district scouting coordinator for the Boy Scouts of America, said the police department will continue to support its three law enforcement posts in West Springfield, McLean and Reston.

He said, however, that all future field trips by the units will require approval from police officials who oversee the program.
