D.C. and Arlington County police Thursday night raided a Georgetown male modeling service that authorities allege was a front for a million-dollar homosexual prostitution outcall business.

Police executing a search warrant at Friendly Models, located at 1658 33rd St. NW, confiscated 11 boxes of business records, including, they said, the names, addresses and telephone numbers of between 500 and 1,000 "preferred customers" around the Washington area.

No arrests were made. However, D.C. police officials said the seized records will be presented to a federal grand jury for investigation and could lead to a number of arrests on prostitution charges.

Authorities said the search warrant was initiated by Arlington police. Earlier this year, police there charged two men allegedly working for Friendly Models with prostitution after they agreed to perform oral sodomy on undercover detectives posing as clients.

Both men were convicted, and Arlington police continued to investigate the model agency.

According to Chapman, Friendly Models had advertised in several small, sexually oriented publications in the city. Vice detectives in Arlington County regularly monitor such publications.

Chapman said encounters with models at Friendly Models were arranged by telephone. Typically, he said, potential clients who called the agency were given detailed physical descriptions of available models.

Chapman said the agency would verify telephone numbers and addresses of potential clients before dispatching models. The models then drove, or were driven by an agency driver, to an appointed location.

Interstate transportation for the purposes of prostitution is a federal offense.

Chapman estimated that Friendly Models was a million-dollar operation. The agency employed approximately 30 models, he said, the youngest of whom was said to be 18.
