A former investigator for a New York state crime committee has testified that Washington area outcall male prostitution representatives have told him that lists of clients have been sold to Soviet and other foreign intelligence agents..

"The Soviet military intelligence was named as . . . one of the foreign agencies that was purchasing information from call services in Washington," former investigator Dale Smith told the New York State Senate Select Committee on Crime, which concluded two days of hearings here today on male prostitution and child pornography.

However, Smith, who has assisted Washington and Arlington police in investigating male prostitution in the last three years, said in an interview with The Washington Post today that he was unable to confirm this allegation.

An FBI official in Washington said today that the bureau has no information to confirm that Soviets or agents from other foreign governments have purchased customer lists from male prostitution services.

However, the FBI official said Soviet agents do attempt to identify officials in sensitive U.S. government posts who are also homosexuals in order to attempt to blackmail them into turning over government secrets.

"We do know that Soviet intelligence officials have been known to frequent gay bars and that sort of thing in an effort to identify defense and other officials who are homosexuals," the FBI official said..

Smith and a District of Columbia police source said today that metropolitan area police officials do not have the resources or the jurisdiction to determine whether the allegations are true.

Smith said he decided to reveal the allegations to the committee because the sale of such sex lists could pose a potentially serious national security problem.

"I feel that it is a matter that ought to be addressed," Smith said in an interview today.

Smith said in the interview that while he posed as someone interested in starting a male prostitution service in the Washington area, an accountant for several male prostitution operations told him that client lists were routinely sold to foreign agents, and that substantial money could be made from that.

In an interview yesterday with The Washington Post, the accountant denied having any knowledge of such sales.

Smith said he was also told about the sale of client lists by the former operator of a Washington area male prostitution operation, who said that he had engaged in such sales himself.

Smith, who has worked for the committee on and off since 1977, declined to disclose his present job. When he worked undercover in Washington, Smith said, he was not formally on the committee staff, but he turned over his findings to the New York committee as well as to police in the Washington area.

Information obtained by Smith was used to help Arlington and D.C. police obtain a search warrant that was used in a May raid on a Washington escort service allegedly involved in male prostitution, according to a District of Columbia law enforcement source. Four people linked to the service have been indicted by an Arlington County grand jury on charges of conspiring to pander.

The committee hearings were conducted by New York state Sen. Ralph J. Marino, who is the coauthor of a New York law that outlaws child pornography.

Aides from Marino's committee said that they have no independent corroboration to substantiate the allegations made by Smith.

Committee counsel Jeremiah McKenna said the panel will submit a report on its findings concerning male prostitution and child pornography to the New York state legislature.

Marino said that law enforcement has not made a big enough commitment to investigate child pornography and male prostitution.
