More than 30 militarized police and National Guard members were patrolling the northern city of Culiacan – the capital of Mexico’s Sinaloa state – when they were fired upon from a house, officials said.
The officers repelled the attack and inside found Guzman’s son, Ovidio Guzman Lopez – who is wanted by U.S. authorities on drug trafficking charges – and three other men, Reuters reported.
Guzman was detained, but soon afterward, his heavily armed supporters surrounded the house, sparking an hourslong gun battle between police and cartel members.
