The United States today offered a $5million (£3.8million) reward for help arresting the leaders of Ireland's Kinahan drug trafficking gang which it likened to some of the world's most notorious crime networks.
Washington also imposed sanctions against gang leaders whom Irish police said had gone from dealing heroin and cocaine in Dublin in the 1990s to operating across Europe.
The US offered the reward for information that would lead to the 'financial destruction' of the Kinahan gang or the arrest and conviction of its leaders, Christy Kinahan Senior and his sons Daniel and Christopher Junior.
A wide range of criminality by the gang, including more than a dozen murders, is estimated to have generated over £833 million (1 billion euros).
Daniel Kinahan, one of the three leaders named by U.S. authorities, has been involved in organising high profile boxing fights in recent years.
He was credited by world heavyweight champion Tyson Fury with helping broker a potential unification bout two years ago.
'As of today the Kinahan transnational criminal organisation joins the ranks of Italy's Camorra, Mexico's Los Zetas, Japan's Yakuza and Russia's 'Thieves In Law',' Gregory Gatjanis, an associate director at the U.S Treasury Department, told a news conference in Dublin.
