Suspected Irish crime boss Daniel Kinahan has appeared before a special non-jury court in Dublin, after an extradition treaty between Ireland and the UAE ended his decade-long exile in Dubai. His court appearance marks a significant development in the long-running effort to bring one of the world's most wanted men to face justice over his alleged leadership of the billion-dollar Kinahan cartel.

Kinahan, 49, has been charged with directing the activities of a criminal organisation between 18 October 2015 and 6 April 2017, and has previously denied all charges against him. The BBC video report examines what is known about Kinahan and his alleged role atop the international drug-trafficking network.
