Mexican authorities have arrested one of the FBI's 10 most wanted fugitives, accused of killing a deputy sheriff last month in the U.S. state of New Mexico.

Police in Mexico say Michael Astorga was taken into custody early Monday while driving in the Mexican border city of Ciudad Juarez. They say he had three guns with him at the time of arrest.

He is being held by Mexican authorities pending extradition to the United States. U.S. Ambassador to Mexico Tony Garza has thanked Mexican officials for their cooperation in the arrest.

Astorga is wanted by the FBI in connection with the shooting death of Deputy Sheriff James McGrane during a traffic stop in New Mexico on March 22.

Astorga is also wanted by New Mexico police for his alleged involvement in a separate murder there last November.
