All were subsequently informed they were under investigation regarding the allegations against them; Proctor himself learnt from his solicitors that the allegation against him included claims that he had stabbed a 12-year-old boy before strangling him to death, and held a press conference afterwards to give details of the police's accounts of the claims to the public, along with the names of those accused on similar charges. Appeals were sent out for further information and witness in regards to the allegations of child abuse and possible homicide, alongside any other potential activities of a similar nature that could have taken place near the Houses of Parliament between the 1970s and 1980s, with events across London and at military establishments, within the same timeframe, also placed under investigation. Public support for the case was increased by the influence of Labour politician Tom Watson, the future deputy leader, who had become a strong campaign supporter for investigations into historic abuse. Watson had met with Beech prior to the start of the operation in regards to his story on Exaro, and remained in touch with him as the operation began, lodging his support of his allegations by accusing those named; when interviewed about the matter, Watson publicly spoke out against Lord Brittan, one of the accused, as being "close to evil" based on Beech's accounts. Conservative politician Zac Goldsmith spoke out in support of the allegations against Lord Brittan, while former Labour politician John Mann MP compiled his own dossier containing allegations against 22 high-profile individuals that he passed on to police. By 2015, police conducted extensive searches for documents and articles that could support the accusations against the accused – the homes of both Bramall in Yorkshire and Proctor on the estate of Belvoir Castle, in Leicestershire, were searched in March, while the home of Lord Brittan was raided, six weeks after his death during the inquiry, with computers, hard drives and documents removed for examination. Despite a search for abuse victims connected to the allegations made by Beech, no credible individuals could be found by police. Shortly after Beech's claims of abuse were announced by Metropolitan Police, another accuser came forward to make further accusations against Lord Brittan and statements of witnessing two murders committed by the group. Although given anonymity and referenced by detectives under the name of "Darren", the Metropolitan Police questioned the validity of the claims, and eventually determined them to be potentially false. Despite this line of inquiry no longer being feasible to pursue, the claims of "Darren" were passed over to Suffolk police to further investigate. Detectives in Suffolk interviewed six people under caution before eventually dropping the case in September 2015 on grounds of insufficient evidence.
