Mexico City ? Mexican police have captured alleged drug lord Carlos Beltran Leyva, just two week after his even more powerful brother was killed in a shootout with troops — back-to-back victories in President Felipe Calderon’s drug war.

The Public Safety office said in a statement Saturday night that Carlos Beltran Leyva was arrested in Culiacan, the capital of the Pacific coast state of Sinaloa, where he and several of his brothers were born and allegedly started their gang.

Two weeks ago, his brother Arturo, reputed chief of the Beltran Leyva Cartel, was killed in a shootout with Mexican marines in the central city of Cuernavaca.

Mexican officials in the past have described Carlos Beltran as a key member of the gang, but it was unclear if he took over as chief of the cartel after his brother died. A third brother, Alfredo Beltran Levya, was arrested in January 2008.

Another brother, Mario Beltran Leyva, is still at large and listed as one of Mexico’s most wanted alleged drug lords.
