An Irish man arrested in connection with the murder of Gary Hutch is due before the courts in Spain today.
The Dubliner was detained in a joint European crackdown on organised crime between Ireland and Spain yesterday.
Cash, documents and a yacht have been seized in the massive operation.
The killing of Gary Hutch in Marbella this time last year is seen as fuelling a series of deaths. In all, 10 people have died in the Kinahan-Hutch feud.
