IN A year-long covert operation, officers from Lisbon’s PSP arrested two men, aged 45 and 49, last week, seizing thousands of grams of heroin, 5,120 euros in cash, a 6.35mm pistol, 600 grams of gold in various forms and three cars. The two drug dealers, who were selling around 1,000 hits of heroin a day from a house in São Domingos de Rana, Cascais, already have criminal records.
