Detector dog Robbie's senses came to the rescue once again as he sniffed out €21,000 in cash hidden in an engine destined for Spain at Dublin Port.
The cash found was mostly small packages of €10 notes.
Revenue officers believe the money is "the proceeds of, or intended for use in, criminal activity".
They said: "Today, at Dublin District Court, Revenue officers were granted a three month cash detention order by Judge John Hughes.
"This followed the seizure yesterday of €21,000 at Dublin Port when, with the assistance of Revenue’s mobile x-ray scanner and detector dog Robbie, officers discovered the cash concealed in an engine destined for Spain.
"The cash is suspected to be the proceeds of, or intended for use in, criminal activity, and is detained by Revenue in accordance with proceeds of crime legislation.
"Investigations are ongoing.
"This seizure is part of Revenue's ongoing work targeting smuggling and shadow economy activity. If businesses, or members of the public, have any information, they can contact Revenue in confidence on Confidential Phone Number 1800 295 295."
