With no sufficient evidence being uncovered or credible witnesses being located by detectives working within Operation Midland, and growing criticism that the investigation was becoming a baseless "witch-hunt", the then–
Commissioner of the Metropolitan Police,
Bernard Hogan-Howe, ordered in February 2016 for an immediate inquiry into the operation to be conducted, a month before its conclusion. Retired judge Sir
Richard Henriques headed the inquiry by the
Independent Office for Police Conduct (IOPC) to determine the overall conduct of officers and detectives during Operation Midland. An extensive check was made into several areas, including how thoroughly police had looked into the allegations they had received from Beech, the treatment detectives had given to those accused by him, and the manner in which evidence had been acquired. Henriques' findings, released in his report in November 2016, uncovered several errors that the Metropolitan Police had made in their investigations, amongst which were: • A failure to conduct a background check on Carl Beech – Metropolitan Police were unaware he had approached
Wiltshire Police two years previously, over claims that he had been a victim of abuse from Jimmy Savile. The inquiry showed that such a check would have alerted detectives that his story to them in 2014 had inconsistencies and could therefore have been identified as being false. • Unfair treatment of the accused – a police policy designed to protect the identity of victims and not their abusers, was chiefly blamed for the group being harshly treated during the operation. The inquiry found that despite the lack of evidence to support Beech's allegations, the accused men were subjected to unwanted media attention after their identities were publicly disclosed, while detectives presumed them guilty without just cause. • A failure to prioritise the search for important witnesses – detectives failed to secure those connected to the accused in the initial weeks due to Beech claiming discomfort on his alleged abuse, while they wasted time seeking out others of significant relevance to the investigation. Those connected to Beech had not been contacted after considerable time, while the search to cross-out possible names connected to those Beech had identified in his accounts as being murdered wasted months of police time. • Search warrants were not legally valid – inaccurate and/or false information was supplied by detectives requesting these from magistrates. The inquiry found that these warrants were severely flawed, as detectives had failed to double-check the information supplied to them by Beech and vouched for him as a "credible" witness, thus invalidating the raids they committed against the homes of the accused.
Analysis Henriques's report condemned the actions of the Metropolitan Police, and voiced support for, amongst other things, providing anonymity to suspected abusers until sufficient evidence had been found. In regards to those accused and investigated by the police, Henriques made it clear in his findings that the men had been "all victims of false allegations" with it firmly noted that the "presumption of innocence appears to have been set aside." The IOPC made clear that, from these mistakes uncovered, future public accountability and reassurances needed to be addressed by British police, with recommendations for possible audio recordings of court hearings for search warrants and renewed efforts to balance the acceptance of a victim's allegations with the objective need to investigate such claims. In response to the findings made in the report, Hogan-Howe admitted that, in his opinion, the mistakes and errors that occurred during Operation Midland stemmed from an over-reaction to "apparent mistakes back in 2012 relating to revelations of very serious and serial child abuse, a mixture of public outrage and propaganda" which "put immense pressure through the Home Secretary, on the police". However, the decision by the IOPC to excuse detectives, and thus not prosecute any officer for their mistakes in Operation Midland, were heavily criticised by Proctor and several politicians – they believed the IOPC had failed in not pursuing charges on possible misconduct in order to maintain that detectives acted in "good faith" with their investigations. Henriques himself noted that, despite his findings and general acceptance of the mistakes made, the inquiries made by the IOPC had been "flawed". ==Investigation impact==
