MEXICO CITY (AP) — The Mexican navy says it has detained a man it believes to be the leader of the Gulf drug cartel in the northern state of Tamaulipas, across the border from Texas.
The navy says the man caught Wednesday identifies himself as Gulf cartel boss Jorge Eduardo Costilla Sanchez. It says it will provide more information Thursday.
Costilla led the Gulf cartel's fierce fight for control of northeastern Mexico against its former enforcer arm Los Zetas.
His arrest is the latest blow to the weakened Matamoros-based Gulf Cartel. It has struggled to keep the Zetas from taking over all of its territory since the two split in early 2010 and began a bloody turf war.
