MOSCOW. May 4 (Interfax) - The work of U.S. and Russian law enforcers to solve a recent 'sex tourism' case is an example of successful cooperation between the two countries, U.S. Ambassador to Russia John Beyrle said.

Between 2002 and 2004, Andrei Mogilyansky, a citizen of Russia and the United States, conspired with Russian citizen Andrei Tarasov and no less than three other persons to form a sex service ring in Russia, employing underage orphan girls as prostitutes. The illegal business, called Berenika, offered adult and underage girls to clients.

Mogilyansky confessed his guilt to a U.S. court. Tarasov and other accomplices were sentenced in Russia in 2004. Tarasov is serving ten years in a Russian penitentiary.

This is an exemplary case of successful cooperation between Russian and U.S. law enforcement, which shows what achievements both countries may have if they work together, the embassy cited the ambassador as saying.

The solution of this case is a result of an international inquiry supervised by the U.S. Immigration and Customs Enforcement Agency, the office of the immigration and customs attache at the U.S. embassy in Moscow, the Russian Prosecutor General's Investigation Committee and the St. Petersburg police, the embassy said.

The U.S. court will pass a sentence in the Mogilyansky case in late July.
