Two children, a boy and girl, who are 6 and 4, who were present were not harmed, Jobe said. The injured woman is their mother, Jobe said.



The gunman was arrested a short time later near Fullerton and Cicero avenues in Chicago, Jobe said. He is being questioned by police and no charges have been filed yet.



The incident began earlier Thursday when the man kidnapped the children and offered to "exchange" the children for the mother at the mall, a law enforcement source said.



When the man pulled up to the mall, he pulled out a handgun and opened fire, the source said, adding that the injuries were not considered life-threatening.



A mall spokeswoman said the incident was confined to the outside of the mall and shoppers were never in danger.
