Sir Cliff Richard has been interviewed by members of South Yorkshire Police in connection with an alleged historical sexual offence, his spokesman confirmed.
The Bachelor Boy singer voluntarily met with officers on Saturday. He was not arrested or charged by police.
A spokesman for the British pop star said: "Today Sir Cliff Richard voluntarily met with and was interviewed by members of South Yorkshire Police.
"He was not arrested or charged. He co-operated fully with officers and answered the questions put to him.
"Other than restating that this allegation is completely false and that he will continue to co-operate fully with the police, it would not be appropriate for Sir Cliff to say anything further at this time."
Police searched the singer's Berkshire apartment last week as part of the investigation into the alleged assault, which it has been claimed occurred at a Billy Graham Christian rally in Sheffield in 1985.
The veteran pop star, who was at his holiday home in Portugal at the time of the police search, denies the alleged offence, saying the claim is "completely false".
Sir Cliff's legions of devoted fans have rallied round him since the allegation became public and are unequivocal in their support of the star.
The fans have launched a campaign to get the veteran singer back in the charts by buying copies of his 1992 Number Seven hit I Still Believe In.
Meanwhile, Sir Cliff's long-time friend Cilla Black has said she is positive there is no truth in the allegations.
The Young Ones star recently pulled out of an event in Portugal giving him the freedom of the city of Albufeira and also cancelled a planned visit to the US Open tennis championships.
He also cancelled an appearance at a charity event at Canterbury Cathedral next month so it was not "overshadowed by the false allegation".
