(ANSA) – Bari, May 31 – Law enforcement officers in the southern Italian city of Bari have arrested two families for the alleged sale of illegal drugs in the area. The two families were resident in the Ceglie del Campo neighbourhood of Bari and stand accused of criminal association relating to the holding of and the sale of illegal substances. The two families are reportedly related to each other. The Carabinieri military police have taken 56-year-old Anna Marino into custody, together with her daughters Giovanna e Isabella Greco, respectively 39 and 35. In addition, her son-in-law Salvatore Decaro, 44 and married to Giovanna Greco was arrested. The 24-year old daughter of Salvatore Decaro and Giovanna Greco and grandchild of Anna Marino, Nicoletta Decaro, is under house arrest. The investigation carried out by the Bari police dismantled a drugs ring managed by the Marino and Decaro families. The families not only purchased the illegal substances, but then also went on to sell them. Operations were being run from the two adjacent houses the people lived in, permitting them to not only ensure 24-hour possession of the substances, but also to sell it at any time of the day or night.
