CHICAGO (WLS) -- Chicago police are warning of an armed robber who is targeting postal carriers.
The person is not taking the mail or packages, but rather their keys!
"It really will impede mail service, because if our carriers are not feeling safe, they're not going to deliver the mail," said Mack Julion, president of the National Association of Letter Carriers Chicago.
It's become a frightening pattern: mail delivery drivers robbed at gunpoint.
As this happens more often, postal carriers are feeling helpless, union leaders said.
