Sixteen people connected to a rehabilitation centre alleged to be a front for a drug syndicate have faced court following an investigation by Victoria’s corruption busters. In September, the operator of St Paul’s drug rehabilitation centre in Strathmore, Tony Dieni — who has regularly given evidence on behalf of those accused of drug offences — was charged with large-scale drug trafficking. Now his grandson, as well as 15 others, some of them former clients of St Paul’s, have faced court on a host of drug-trafficking and perverting the course of justice charges.
