Police officers have been warned they could face disciplinary action over their dealings with the BBC before the highly public five-hour search of Sir Cliff Richard's home following an allegation of historic child abuse.
The corporation came under fire from politicians, senior police and one of its former journalists, Sir Michael Parkinson, after it broke the story of the probe into the 73-year-old singer, who was reportedly preparing to return from holiday in Portugal to face police questioning over the affair.
The College of Policing - which has drawn up an ethical code for officers - said South Yorkshire police and the BBC had to explain the circumstances of how the Corporation was made aware of the search at the NZ$6 million home, which it said was normally a "closely guarded secret".
"If the information was an unauthorised disclosure from within policing then it would be contrary to the Code of Ethics and the person concerned should be held to account," said chief constable Alex Marshall, the college's chief executive.
South Yorkshire police has complained to the BBC and accused it of breaching its own editorial guidelines over filming of the search, which followed an allegation of a sexual assault on a boy under the age of 16 at a Billy Graham evangelical gathering in Sheffield in 1985.
