A Dublin based Brazilian man and a Sao Paolo woman have been remanded in custody after airport customs officers intercepted a case with €740,000 worth of cocaine.
Dublin District Court heard that the drugs were partly in liquid form, in shampoo bottles.
Gardai arrested Jefferson Pedrucci, 32, of Carrigmore Glen, Saggart, Dublin, and 28-year-old Pamela Da Silva, who is of no fixed address, after their flight landed at Dublin Airport on Thursday evening.
They were charged with unlawfully possessing and importing cocaine and having it for sale or supply.
Ms Da Silva has an additional charge for carrying false immigration documents.
She was granted legal aid, and her solicitor John O'Doherty told Judge Simms there was no application for bail at this stage.
Judge Simms remanded her in custody to appear again on Friday.
Garda Ross Brierley told the court that her co-accused Mr Pedrucci made no reply to the charges.
Garda Brierley objected to bail due to flight risk fears and added that Mr Pedrucci could face a sentence of up to 14 years.
He allegedly travelled with a female companion from Sao Paolo via Lisbon and landed at Terminal One just after 4.30 pm on Thursday.
Custom officers X-rayed their suitcases, containing 8.5 kilos of cocaine worth €600,000. In addition, there were two bottles of shampoo, weighing two kilos, which was found to be "cocaine in liquid form" and valued at €140,000.
Garda Brierley said the man was caught red-handed.
The garda confirmed Mr Pedrucci denied knowing the contents of suitcases he claimed were given to him by people in Brazil.
He also maintained the shampoo bottles were for a friend's wife, a hairdresser in Ireland.
Judge Simms ruled that the objections were well made, and he refused to grant Mr Pedrucci bail.
He was remanded in custody to appear again on Friday.
