Joaquin Guzman, Mexico¡¯s notorious drug dealer commonly known as El Chapo, escaped from a maximum-security prison in a mile-long tunnel.

Based on the height, width and extension of the tunnel, the estimated amount of earth removed would have filled 379 lorries. The air-conditioned tunnel provided enough room for a speedy exit during which Guzman disposed of a bracelet that only he and a few other high-risk inmates had to wear. Authorities believe that there may have been a motorcycle waiting for his escape.

All of Mexico¡¯s security forces coordinated to capture the drug lord, with a 3.8 million US dollar on offer and 34 people being questioned within four days.

Difficult words: notorious (well known for doing something bad), extension (length), inmate (prisoner).
