Investigators probing the Hillsborough disaster are reviewing evidence relating to five more suspects.
The Crown Prosecution Service (CPS) said it expects to announce within the next three weeks whether charges will be brought against two suspects from West Midlands Police, the force that investigated the aftermath of the 1989 disaster.
The Independent Office for Police Conduct (IOPC), previously known as the Independent Police Complaints Commission, is also reviewing evidence relating to three former South Yorkshire Police officers.
Officials are due to make a decision on whether they will be referred to the CPS so criminal charges can be considered.
