Four Irish men remain in custody in southern Spain after a joint operation by gardaí and Spanish police uncovered drugs worth €3.4 million.
Gardaí say the cannabis herb was found hidden in lettuce pallets on a lorry that was bound for Ireland.
The operation happened on May 6th near Malaga, but details of the operation were only released last night.
The Irish men - aged 56, 45, 35 and 33 - have already appeared before a Spanish magistrate.
A 27-year-old Romanian man was also arrested.
All five men remain in custody.
Gardaí are describing the operation as a "significant blow" to organised crime gangs.
Assistant Commissioner John O’Driscoll said: "We are very grateful to the Spanish law enforcement authorities for their ongoing and very productive cooperation with the Garda Síochána in tackling organised crime groups operating in both Spain and Ireland.
"This Operation has dealt another significant blow to the capacity of the organised crime groups involved to continue their trade in controlled substances.”
