Senator Sue Errington was robbed yesterday in Indianapolis. Two men, one who was armed with a pistol, mugged Errington about 9:30 p.m. Monday at CVS as she was going to her car. One of the robbers hit Errington in the eye with his fist as she clutched her purse, knocking her to the ground. Errington was treated and released at St. Vincent Hospital, receiving seven stitches on her eyelid for a cut. Also, she received a fracture, that did not require surgery.
