The former operator of several massage parlors and out-call massage services in Washington and Northern Virginia pleaded guilty in federal court yesterday to one count of interstate transportation of a female for purposes of prostitution.

Karl Klaus Bolle, 53, who lives in Virginia, faces five years in jail, a $5,000 fine or both as a result of the guilty plea.

The charge against Bolle stems from a raid conducted a year ago by federal law enforcement officials on three massage parlors, Bolle's Fairfax office and the home of a manager of one of the massage parlors and out-call services. Sources said at the time that records seized in those raids indicated that the massage parlors and out-call services did more than $1 million in business a year.

Since the raids, those businesses have been closed down, an FBI spokesman said.

U.S. District Judge Howard F. Corcoran, who accepted the guilty plea from Bolle yesterday, has not set a date for sentencing in Bolle's case. Four women who managed individual businesses for Bolle were sentenced to three years probation after they each pleaded guilty to interstate transportation of women for prostitution, the FBI spokesman said.
