A Mexican official says the army has captured the suspected successor to a top Sinaloa drug cartel leader slain in a gunbattle with soldiers in 2010.

President Felipe Calderon's security spokesman, Alejandro Poire, says the unnamed suspect replaced Ignacio "Nacho" Coronel, the cartel's reputed No. 3 capo gunned down in Guadalajara in July 2010. Poire did not identify the captured suspect or give any more details on the army operation.

The Mexican army said in a statement late Thursday that they had detained one of the main leaders of the Sinaloa cartel, led by Joaquin "El Chapo" Guzman. They said more details would be provided Friday morning.

The death of Coronel has been the biggest strike against the Sinaloa Cartel during Calderon's government.
