A massive manhunt is on for to nab Mexico's most notorious drug lord Joaquin "El Chapo" Guzman, who managed to break out of a maximum security prison in Mexico last Saturday night, for a second time.

Investigators found that "El Chapo" Guzman used a kilometre-long tunnel built under his bathroom to escape from the Altiplano prison. The tunnel, which was both well-illuminated and amply ventilated, ended at an abandoned property.

The photos of the abandoned property, where the escape tunnel used by Guzman ended, indicated it was inhabited by more than two men, who might have facilitated the Mexican druglord's escape from prison.

The police also found mattress and clothing in the abandoned house. El Chapo's escape from the maximum prison for the second time has now made him a legendary figure.

When Guzman escape from the high-security prison in January 2001, it took investigators over a decade to catch him. During that time, he went on to marry an 18-year old beauty queen - Emma Coronel - with whom he had two daughters, before he was arrested again in February 2014.

Here are 10 things to know about the Mexican drug lord, who has once again become one the most wanted men in the world.

1. 'Osama Bin Laden of Drug Trafficking': After the US Navy seals killed Al Qaeda leader Osama bin Laden in 2011, Guzman became the world's most wanted man. Despite facing several charges in the US, Guzman has managed to avoid extradition to the United States. A US official once dubbed him "Osama bin Laden of drug trafficking."

2. World's Richest Gangster: The Sinaloa Cartel leader was once listed in the Forbes Billionaires List, but was dropped from the World's Wealthiest Men List on grounds that his money was 'sketchy.'

3. Sinaloa cartel operates in 5 continents: A CNN report in 2014 stated that El Chapo Guzman's Sinaloa drug cartel is one of the most powerful drug syndicates in the world operating in five continents, including Asia. The report stated that the drug cartel's reach extended from Sinaloa to Mexico's Durango and Chihuahua states, besides Russia, Australia and Sierra Leone.

4. Notorious Drug Lord is a loving husband: Following Guzman's arrest in 2014, a report revealed that when the Mexican marines raided El Chapo's apartment, the notorious criminal was busy making breakfast for his wife Emma Coronel and their twin daughters.

5. Guzman's Love Story: The Mexican drug lord has been married at least three times, but it is largely claimed that Guzman was madly in love with Emma.  A report in The Daily Beast noted that Emma Coronel Aispuro was crowned beauty queen at a local pageant in 2007 after El Chapo Guzman arrived in the town with hundreds of gunman to host a lavish party to announce his intention to marry her. 

6. Chicago's Public Enemy No. 1: In 2013, the Chicago Crime Commission named Joaquin "El Chapo" Guzman as the city's new Public Enemy No. 1 after investigations found that the Sinaloa cartel supplied majority of the narcotics to the city. 

7. Guzman had $7 million bounty on his head: Before his arrest in 2014, Mexican authorities had announced a bounty of $5 million on Guzman. Similarly, US authorities had put a prize of $2 million on any information about him. With his recent escape, it is only a matter of time that the bounty rises.

9. El Chapo is a reference to his height: Because of his height, Guzman's friends named him El Chapo, which means 'shorty', when he was a teenager. He is believed to be 5.6 feet tall.
