PLEASE NOTE: EDIT CONTAINS MATERIAL THAT WAS ORIGINALLY 4:3<br/> <br />The identity of Mexican drugs kingpin Joaquin 'Shorty' Guzman was publicly confirmed by Mexican authorities on Tuesday.<br/> <br />He's undergone DNA and forensic tests to establish that police had got their man.<br/> <br />Guzman is being held in a maximum security area at a jail outside the capital.<br/> <br />But U.S hopes of trying him on narcotics and arms trafficking charges have suffered a blow.<br/> <br />Guzman's lawyers have got an injunction blocking any move to extradite him.<br/> <br />It's unclear how long the injunction will stay in force but it raises the possibility of a legal battle that could go on for years.<br/> <br />Guzman's Sinaloa cartel has smuggled billions of dollars of drugs into the U.S. and fought brutal turf wars with other gangs across Mexico.<br/> <br />His arrest on Saturday has ended his time as one of the world's most notorious organised crime bosses but his eventual fate is far from clear.
