TEGUCIGALPA, Honduras (AP) — The U.S. Treasury Department has imposed financial sanctions on three Honduran men, three coffee companies and a cattle and dairy operation under the Foreign Narcotics Kingpin Designation Act.

The men allegedly lead the Los Valles drug gang, which allegedly traffics tons of cocaine per month to the United States.

A sister of the three men was arrested in the U.S. on federal drug charges in July.

Honduran authorities seized more than 40 properties belonging to the Los Valles gang on Sunday.

The department says Miguel Arnulfo Valle Valle, Luis Alonso Valle Valle and Jose Reynerio Valle Valle operate “as a close-knit family business.”

Wednesday’s designation prohibits Americans from conducting financial or commercial transactions with the men and the companies, and freezes their U.S. assets.
