According to the PJ police, the heroin was transported by the arrested man, 28-years-old from an African country, hidden within the structure of a suitcase.
The Judiciary Police said that if the drug reached illicit distribution channels, it would be enough for at least 37,000 individual doses, worth €1.1 million.
The arrest, according to the PJ, occurred during regular inspections of passengers from countries considered to be a risk, to prevent the introduction of drugs to Portugal and other European countries through international airports.
