Former Chief Superintendent David Duckenfield, the match commander at the 1989 Hillsborough disaster, will face retrial on a charge of gross negligence manslaughter.
Duckenfield, 74, had denied the gross negligence manslaughter of 95 Liverpool fans at the FA Cup semifinal against Nottingham Forest at Hillsborough on April 15, 1989. A 96th victim, Tony Bland, died more than a year after the disaster and under the law at the time, no prosecution can be brought.
After a 10-week trial at Preston Crown Court ended last April, a jury of six men and six women were told by Judge Sir Peter Openshaw they could return a majority verdict of at least 10-2, after they were unable to return a unanimous decision before being discharged.
