The Roselands man faces four charges and will appear before Sutherland Local Court on 21 January. Police say the elaborate phone scams are happening more frequently and are targeting people across NSW. They believe the scam is linked to transnational organised crime syndicates. The scammers are using a technique called called ID spoofing, where the call appears to be coming from a number used by the government agency they say they represent. The caller purports to be from the police force or a government agency and demands money under threat of violence or arrest, police say. They convince the person to hand over personal information and give instructions to either purchase gift cards or withdraw cash and hand it over to a particular person.
