More than 150 complaints or allegations against former police officers involved in the Hillsborough disaster are still being investigated 33 years later.
Details emerged after the West Midlands branch of the National Association of Retired Police Officers met the Independent Office for Police Conduct.
They were told 68 complaints and six misconduct cases involve staff and retired officers from West Midlands.
The rest involve ex-officers and staff from Merseyside and South Yorkshire.
Ninety-seven Liverpool fans died as a result of the crush at an FA Cup semi-final match at Sheffield Wednesday's stadium on 15 April 1989.
