Sir Norman Bettison's role in the 1989 disaster, which cost 96 Liverpool fans their lives, could be further investigated by the Independent Police Complaints Commission
Bettison was referred to the watchdog alongside former employers South Yorkshire Police whilst West Midlands Police, who led the botched investigation in the aftermath, referred themselves.
If found guilty of criminal conduct by the IPCC, the individuals involved could be brought before the CPS [Crown Prosecution Service] for prosecution.
A spokesman for the IPCC said: “We have conducted our own review which will undoubtedly cover the referrals we have received and possibly more.”
Bettison apologised last month after insisting Liverpool fans "made the job of the police harder than it needed to be" just days after the panel's report was released.
The former Merseyside police chief recently announced his intention to retire next year with a full pension, though criminal charges could yet be brought against him.
