Following the Independent Police Complaints Commission (IPCC) investigation, the organisation brought charges against Sir Norman Bettison, a former Chief Inspector and Superintendent of South Yorkshire Police, Peter Metcalf, the Solicitor of South Yorkshire Police, former Chief Superintendent Donald Denton and former Detective Chief Inspector Alan Foster.
Four of the six people now on trial for Hillsborough are facing action in the context of the Hillsborough Disaster investigation by the South Yorkshire Police Service.
Former Merseyside top police officer Norman Bettison is among the IPCC indictments of Hillsborough.
The former policeman is charged with manslaughter through gross negligence.
The accused are Graham Mackrell, Secretary of Sheffield Wednesday Football Club, and former Chief Superintendent David Duckenfield, who was captain on the day of the disaster.
Two other charges arise from Operation Resolve, the investigation into the causes of the 1989 disaster.
The prosecution decided that there was insufficient evidence to indict two SYP officers who were also involved in the change process, the IPCC said.
This is the first time the state has indicted suspects who are alleged to have been involved in the disaster in the 1989 FA Cup semi-final in which 96 Liverpool football fans died.
Decisions on two West Midlands Police suspects who were referred to the CPS are still under review, the watchdog added.
Earlier, in 2000, families had filed a private prosecution that proved unsuccessful.
IPCC Vice Chairperson Rachel Cerfontyne said: “The CPS has announced indictment decisions for six of the eight suspects formally referred by the IPCC in January of this year. We have also referred two others.
“We will work closely with the CPS on the indictment case and provide any further assistance necessary while the decisions on the remaining IPCC files are under review. “Following a criminal case, we will consider whether former police officers, including all those who have been referred to the CPS for a decision on an indictment, would have had cases of misconduct if they had still been on duty.
“The evidence supporting these findings will be presented in the final investigation report”.
A spokesman added: “Evidence from these individual investigations is now being considered and will be detailed in the more comprehensive Hillsborough report on the independent IPCC investigation and the investigation of the conduct of SYP officers on the day of the disaster.
The IPCC stated that its investigation of 170 allegations of misconduct by police officers both on the day of the disaster and after the disaster was nearly complete.
