Customs Officers arrested a man after they seized 15 kilos of cannabis at Dublin Port on Saturday. The drugs are thought to be worth about €300,000.

A British man was detained after the Revenue sniffer dog 'Holly' gave a positive reaction to a vehicle that came off the late evening ferry from Holyhead.

The vehicle was scanned by the Customs Mobile X-Ray Scanner and found to contain a false floor beneath which officers discovered the drugs.

The man was later arrested and investigations are continuing.
