A 28-year-old man was detained by the Judicial Police on Wednesday 11 November while allegedly trying to introduce drugs into Porto Prison.[1][2][3] The Judicial Police announced the detention on Thursday 12 November.[4] The arrest was carried out by the Judicial Police’s Northern Directorate with the Prison Guard Corps over suspected aggravated drug trafficking.[1][3][5] He had gone to the prison in the early afternoon to visit an inmate.[1][4] During the visit he took off the trainers he was wearing and handed them to the inmate, who exchanged his own footwear in the same way.[1][4] The exchange was detected and the footwear was seized.[6][4]

Inside the trainers officers found several wraps containing suspected narcotics.[1][4] Police examinations confirmed more than 100 grams of drugs, namely cannabis resin and cocaine.[1][5][4] The episode occurred at the Custoias prison complex, where prison guards detected the handover and the Porto Judicial Police detained the visitor.[2]
