Mexico has arrested a third man wanted over the 2010 murder of a U.S. Border Patrol agent whose death drew attention to a botched operation to track guns smuggled to Mexico that embarrassed the U.S. government.

Mexican police in the northwestern state of Sinaloa said they had captured Ivan Soto Barraza, suspected of participating in the murder of U.S. agent Brian Terry, who was killed in a shootout in the Arizona borderlands in December 2010.

The killing of Terry was linked to a U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives sting operation dubbed “Fast and Furious,” which allowed weapons to slip across the border to Mexico.
