A 61-year-old massage parlour worker has been charged with sexually assaulting multiple clients at businesses located in shopping centres on the Gold Coast and in Brisbane. The alleged incidents involve a 17-year-old girl at a Southport location in December and a 29-year-old woman at Chermside in August. Police believe there may be additional victims and are urging witnesses to come forward, with the accused scheduled to appear in court in February.
