Officials have been warning that the Blue U.S. Postal Service mailboxes are being targeted and checks could be stolen. But there’s another troubling trend associated with the robberies — armed assaults.
At least a dozen USPS workers have been assaulted in Massachusetts since July, officials said, adding that at least 10 of them were related to USPS Arrow Keys. Additionally, suspects in six of the robberies were armed with a knife, firearm or both, officials said.
