Key police footage of the Hillsborough football disaster is “missing”.
Pete Weatherby QC noted the “unexplained ten minute gap” in one of the police tapes.
“There may be integrity issues here,” he added.
Weatherby, who represents families from the Hillsborough Justice Campaign, was speaking earlier this week at a pre-inquest hearing into the disaster.
Some 96 Liverpool football fans died as a result of a crush at Sheffield’s Hillsborough football ground in 1989.
Inquest verdicts of accidental death were quashed after new reports highlighted police failings on the day and a subsequent cover-up. New inquests are due to begin on 31 March in Warrington.
The news of missing footage follows revelations that officers altered police statements in the aftermath of the disaster.
An independent panel report last year found that nearly 200 police statements were altered after the disaster—164 substantially.
Since then the Independent Police Complaints Commission (IPCC) has said over 70 more police statements may have been altered.
And outgoing IPCC chair Deborah Glass said there was evidence that “amendments may have been made” to fans’ evidence.
