Four Russians were arrested by the Federal Bureau of Investigation of the United States over charges of money laundering and collusive fraud, according to the Russian Consulate General in New York.

"One of them was arrested in Boston and transferred to New York. Another two, as the information of the Federal Bureau of Prisons showed, were arrested in Los Angeles, while the location of the forth is being found out," the consulate general wrote on Facebook Monday.

Russian media Sputnik reported that the arrests were related to a wire fraud and money laundering case revealed by the U.S. Justice Department last month, in which 25 persons, including these four, were involved in a car fraud of more than 4.5 million U.S. dollars.

The Russian embassy in the United States said in a statement that they were closely following the situation and had referred to the U.S. State Department for clarification of the matter, while trying to establish direct access to the detainees.
