Mexico president calls for ‘transparency’ amid secrecy over Sinaloa cartel arrests

US announces arrest of two leaders of organised crime group as Mexican authorities say they were in the dark

The Mexican president, Andrés Manuel López Obrador, has called for “transparency” after the sudden and secretive arrests by US authorities of two top leaders of the Sinaloa cartel, one of Mexico’s most powerful organised crime groups.

Ismael “El Mayo” Zambada García, 76, founded the Sinaloa cartel with Joaquín “El Chapo” Guzmán Loera, and has been a top target of US law enforcement for decades, with a $15m bounty on his head.
