A ninth person has been jailed in connection with the interception of a yacht carrying cocaine with a street value of more than £160m off the south-west coast of Ireland.

Gardaí were involved last year in seizing €700m worth of drugs, targeting 621 crime gangs, and tracking down more than 9,000 missing persons.

A sixth suspect being hunted by investigators probing the alleged plot to smuggle €100m of cocaine across the Atlantic in a yacht has handed himself in.
