An appeal for thousands of people who were in the crowd on the day of the Hillsborough Disaster to come forward.
It is claimed there are so many inconsistencies in the original evidence that more eye witness accounts are needed..
Those inconsistencies are in the statements given to officers from West Midlands Police which later formed part of the now discredited Taylor report.
Andy Bonner reports.
The police watchdog is appealing for witnesses as part of its investigation into the aftermath of the Hillsborough disaster.
The Independent Police Complaints Commission is investigating allegations of a police cover up which attempted to shift the blame on to the victims.
The IPCC says it has uncovered inconsistencies between witness statements and police questionnaires filled out in 1989.
