South Yorkshire Police searched the house in the Sunningdale area on Thursday, after an allegation was made regarding a sex attack in the 1980s on a boy aged under 16.Sir Cliff, 73, has strenuously denied the claim."The allegations are completely false. Up until now I have chosen not to dignify the false allegations with a response, as it would just give them more oxygen," he said, in a statement."However, the police attended my apartment in Berkshire without notice - except, it would appear, to the press."On Friday, South Yorkshire Police also released a statement about the media coverage of the case."When a media outlet contacted SYP with information about an investigation, we took the decision to work with them in order to protect the integrity of that investigation," the statement said."Since the search took place, a number of people have contacted the police to provide information and we must acknowledge that the media played a part in that, for which we are grateful."Sir Cliff, while not currently in the UK, has said he will cooperate fully with the investigation.
