“Criminal groups like the KOCG prey on the most vulnerable in society and bring drug-related crime and violence, including murder, to the countries in which they operate.”

Kinahan has always denied that he is part of an organised crime group.

In a press conference held by Garda Commissioner Drew Harris on Tuesday, it emerged that the Irish police had seized £6.3m in cash from the Kinahans since 2015, along with 48 firearms, 2,212 rounds of ammunition and almost £17m worth of drugs. Harris also called on athletes linked to the Kinahans to ‘think of their fans and reputation’, adding: “What was implicit is now explicit.”
