After a seven-week trial at Preston Crown Court, the jury deliberated for three days before returning their conclusion on Thursday afternoon.
They found Duckenfield not guilty on the charge of manslaughter by gross negligence of 95 of the 96 children, women and men who lost their lives as a result of the events at the FA Cup semi-final between Liverpool and Nottingham Forest on April 15, 1989.
Due to the law in 1989, the former chief superintendent was not charged with the manslaughter of Tony Bland, because he died more than a year and a day after the disaster occurred.
