According to the PJ, the arrest was made due to the detection by the Tax and Customs Authority services at Lisbon Airport of a suitcase that was not collected after the arrival of the flight in which it was transported. In its interior were hidden about 5.5 kilos of heroin.

"From the steps that were immediately carried out, it was possible to identify and locate the passenger who transported the suitcase to Lisbon, further ascertaining that he was in possession of another suitcase containing the same quantity of that type of narcotic product", clarifying that the total amount of “high purity heroin” seized amounts to approximately 11.050 kilos.

Another note from the Public Ministry (MP) also indicates that "the defendant arrived at Lisbon Airport on a flight from South Africa".
