Two Mexican federal officials say alleged cartel capo Hector Beltran-Leyva is believed to have been captured.

The officials say DNA testing is being done to confirm the suspect's identity.

Beltran-Leyva is leader of a cartel named after his brother Arturo, who was killed by Mexican troops in a shootout in late 2009. The U.S. government says it is responsible for trafficking cocaine, marijuana, heroin and methamphetamine.

Two other brothers are in prison for their involvement in the cartel.

Hector Beltran-Leyva has been indicted in courts in the District of Columbia and New York. U.S. authorities had offered a reward of up to $5 million for information leading to his capture.
