Celebrities and politicians were protected from child sex investigations because hundreds of police intelligence files were kept so secret that investigating officers could not access them. Information on famous suspects was marked secret" or "restricted", allowing only a small number of officers to access it, to offset the risk of police officers or staff leaking the information to the media. The burying of information is understood to have helped serial offenders such as Jimmy Savile and Sir Cyril Smith MP escape prosecution for decades. The problem has emerged in a review of police information handling by HM Inspectorate of Constabulary, in the wake of the Jimmy Savile scandal. Since the exposure of the former TV presenter as Britain's most prolific child sex offender, police have been inundated with reports from members of the public of "historical abuse", often by prominent politicians, celebrities and VIPs. The National Association of People Abused in Childhood said the practice had hampered investigations that could have prevented further abuse. John Bird, spokesman for the charity, said: "It is certainly the case that in the past the police put protecting celebrities above child protection. However we do think that now there is a clear drive to learn from these mistakes and get it right in the future."
