Revenue officers seized cannabis worth an estimated €23,000 and a pit bull puppy in separate searches at Dublin Port yesterday.
The male was immediately arrested on board the boat from Holyhead and investigations are ongoing with a view to prosecution after 1.15kg of the drug were seized.
The detection was made when officers stopped the man after Revenue dectector dog Robbie was alerted to the scent of the drugs.
In a separate incident on the same day, officers seized a nine-month-old pit bull puppy who was travelling to the UK with a man who did not have a pet passport for the dog, as is legally required.
The puppy was transferred into the care of the DSPCA, where he is receiving veterinary attention and a follow up investigation is now underway.
Revenue officers keep a keen eye on dogs that may be used in illegal puppy trading.
It comes after another haul of herbal cannabis worth an estimated €120,000 was discovered by Revenue officers at Portlaoise Mail Centre.
