An Irish man arrested in connection with the murder of Gary Hutch is due before the courts in Spain.
The Dubliner was detained in a joint European crackdown on organised crime between the two countries 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 the start of the deadly Kinahan Hutch feud, which has claimed ten lives.
