BOSTON (WBZ NewsRadio) – Boston police are warning about a new scam that pushes people to withdraw cash or buy gold and silver to “protect” their savings. The thieves will message a victim pretending to be from the government or tech support, then tell the victim their bank account is hacked and they have to withdraw funds or buy precious metals to keep their money safe. The scammers will even send couriers to pick up the metals from victims’ houses.
