Sun-Times file Police are warning residents of a man who attempted to lure a 12-year-old girl into his truck last week in South Chicago. The girl was walking west on 81st Street near Exchange Avenue about 8 p.m. Thursday when the man began following her in a truck, according to Chicago police. The man, between 30 and 40 years old, honked his horn and waved his arm towards the girl directing her to come to his vehicle, police said. He then fled in his truck, which may be silver-colored, according to police. Anyone with information is asked to call Area Two detectives at 312-747-8271.
