Daniel Morgan was a private investigator who was killed with an axe in a parking lot. The murder was committed decades ago, but it has never been solved.
The Metropolitan Police Service of London reported today that it discovered documents that had been sitting in a locked cabinet for a while.
An independent investigation of how the Met handled the case in 2021 discovered systemic corruption in the way the force hid or ignored its mistakes.
Police said the paperwork, which it did not provide details about, should have been given to the Daniel Morgan Independent Panel (DMIP) before its report.
The dozens of documents sprawling more than 160 pages were found in January this year and a ‘careful’ assessment began the following month.
Assistant Commissioner Barbara Gray said: ‘We fully acknowledge how unacceptable and deeply regrettable this situation is.
‘We are working to understand what has taken place and any impact. We apologise to the family of Daniel Morgan and to the Panel.’
