The incidents highlighted the difficulties involved in cracking down on the drug cartels which control large parts of Mexico.
Guzman’s father, known as El Chapo, was the head of the Sinaloa drugs cartel before he was extradited to the US in 2017.

El Chapo was convicted by a New York court in 2019 of 10 counts of drug trafficking, firearms and money laundering charges, and is currently in a US maximum security prison.
During his 25-year leadership of Mexico’s Sinaloa cartel, he went from being a small time marijuana smuggler to being the head of the “largest drug trafficking organisation in the world… with thousands of members”, US authorities said at the time.
It smuggled around 154 tonnes of cocaine into the US, as well as heroin and methamphetamine – earning El Chapo and his associates $14bn (£11.6bn), they added.
