CHICAGO - A postal worker in Chicago was shot in the leg late Tuesday after a resident along his postal route allegedly became angry that he was delivering the mail too late.

Police said Denny Robinson, 31, was delivering mail around 6:30 p.m. in Chicago's West Pullman neighborhood when he was shot in the thigh. Robinson was taken to a nearby hospital for treatment for the non-life-threatening injury.

Authorities said witnesses reported hearing a person yelling the postal worker was delivering the mail too late and then heard a shot.

Police News Affairs Officer Tom Polick said nobody could say where the shot came from.

Wanda Shipp of the U.S. Postal Inspection Service said Robinson was delivering mail after the normal 5 p.m. quitting time because Monday was holiday, and volume was heavier than normal.
