Police hunt for drug kingpin

Sinaloa cartel leader's second prison break 'an affront to the state'

Mexican security forces hunted early Monday for drug kingpin Joaquin "El Chapo" Guzman as authorities investigated whether he had received inside help to escape prison through a tunnel under his cell's shower.

It was the second time in 14 years that Guzman, the head of the powerful Sinaloa drug cartel, managed to flee a maximum-security prison, dealing an embarrassing setback to President Enrique Pena Nieto.
