Two smugglers have been arrested in recent days at Rome's Fiumicino airport after arriving via Dubai, they said.
One was an 19-year-old Slovak with two kilos (4.4 pounds) of cocaine stashed in a false bottom of his suitcase who had departed from Rio de Janeiro, while the other was a Nigerian who hid vials of cocaine in his socks.
The street value of the two seizures was put at around half a million dollars (441,000 euros).
The smugglers do not leave Dubai's transit lounge, as this would expose them to customs checks, the police said in a press release.
"The trick aims at providing the smuggler with an itinerary that looks unsuspicious to police officers," they said.
