The man offered to give the boy a ride in his car if the school bus did not show up, the sheriff’s office said. The man then approached a girl waiting at the same stop, offered her a ride and asked if she wanted to go for coffee.

The man was described as white, 30-40 years old and between 5-foot-10 and 6-feet-tall, authorities said. He had short, blond hair and wore a black coat, black jeans and a had hat or hood over his head.

The sheriff’s office also released footage from video surveillance of the man and asked to public to help identity him.

Anyone with information was asked to call the sheriff’s office at (708) 865-4896 or (847) 635-1188.
