Police are searching a property in Berkshire belonging to Sir Cliff Richard in relation to an alleged historical sex offence.
Items were removed from the property in the Sunningdale area for investigation. No arrests have been made.
A spokesperson for South Yorkshire Police said the allegation involved a boy under the age of 16 and dated from the 1980s in the South Yorkshire area.
Sir Cliff, 73, was not present at the time. He is rumoured to be in Portugal.
The BBC reports that eight plain clothes police officers arrived at the private estate in unmarked cars mid-morning.
Sir Cliff released a statement this afternoon after widespread media coverage of the search on his home, saying: “For many months I have been aware of allegations against me of historic impropriety which have been circulated online.
“The allegations are completely false. Up until now I have chosen not to dignify the allegations with a response, as it would just give them more oxygen.
"However, the police attended my apartment in Berkshire today without notice, except it would appear, to the press.
"I am not presently in the UK but it goes without saying that I will co-operate fully should the police wish to speak to me.
"Beyond stating that today's allegation is completely false it would not be appropriate to say anything further until the police investigation has concluded."
Thames Valley Police confirmed that it had helped the South Yorkshire force with the execution of a search warrant at the address in Sunningdale, Berkshire.
