South Yorkshire Police have "apologised wholeheartedly" to Sir Cliff Richard after its investigation into the singer was dropped.
The initial raid on Sir Cliff's home in Berkshire was broadcast live on TV following a controversial agreement between the BBC and the force.
In a statement, South Yorkshire Police said:
We apologise wholeheartedly for the additional anxiety caused by our initial handling of the media interest in this case.
Following an initial allegation received by the force in April 2014, South Yorkshire detectives have explored and gathered all information available and carried out a thorough and detailed investigation, which has covered the UK and abroad.
The investigation, which has spanned two years, is estimated to have cost in the region of £800,000, including staffing costs.
After careful consideration of the evidence provided to them, the CPS has concluded that no further action should be taken against the man due to there being insufficient evidence to prosecute.
South Yorkshire Police accept the decision of the CPS in this case and all those involved have been informed.
The Crown Prosecution had said there was "insufficient evidence to prosecute" the singer.
The Crown Prosecution Service has said they will not take further action against Sir Cliff. Here is what has happened so far.
The CPS says its investigation found 'insufficient evidence' to prosecute the 75-year-old.
