A man who allegedly took his two daughters from the Boyden-Hull Elementary school last Monday was arrested yesterday in Chicago. Chi-Sheng Liu was involved in a custody dispute with his wife, Grace, who had filed for divorce. Sioux County authorities received information yesterday (Friday) morning that Liu might be at O’Hare Airport with the two girls, 9-year old Gini and 7-year Old Tina. The sheriff’s office contacted Chicago police and Liu was arrested a short time later on a warrant charging him with violating a custodial order. Authorities say the two girls were reported safe and in good condition.
