Prince George's County Police say a postal worker was robbed while working at the Largo-Kettering Post Office Wednesday evening.
The incident comes after two recent attacks on postal workers who were delivering mail -- one mailman was gunned down and killed in Landover and another was assaulted and robbed in D.C.
"People are just evil these days, robbing a postal worker," a customer told News4. "They're just doing their jobs."
Police say a suspect entered the post office in Upper Marlboro around 7 p.m. Wednesday and demanded money, then left with an undisclosed amount of cash. No one was injured in the incident.
The suspect is described as having worn an all-black jogging outfit. If you have any information, call police.
