The arrested man is being held at Ballymun Garda Station under Section 2 of The Criminal Justice (Drugs Trafficking) Act 1996.

The drugs were found hidden in false panels of six boxes of a cargo package. The package had been labelled as containing clothing. It originated in Malaysia and was set to be delivered to an address in Dublin.
"These operations are part of Revenue's ongoing work targeting smuggling and shadow economy activity," a Revenue spokesperson said. "If businesses, or members of the public have any information, they can contact Revenue in confidence on Confidential Phone Number 1800 295 295."
