Police search for escaped Mexican drug lord Joaquin Guzman

Mexican drug lord Joaquin Guzman, known as El Chapo or "Shorty", used an elaborate 1.5 km tunnel to break out of a maximum security prison, officials say.

Guzman was last seen in the showers of the jail on Saturday.

It is the second time he has escaped from a top security prison.
