The U.S Postal Service is offering a reward up to $25,000 for tips leading to the arrests of four people for robbing a letter carrier at gunpoint last year on the South Side.
The suspects wore ski masks when they confronted the carrier around 6:40 p.m. Nov. 22 in the 7700 block of South Champlain Avenue in Park Manor, according to the U.S. Postal Inspection Service.
