Sir Cliff Richard was interviewed under caution at the weekend by South Yorkshire Police detectives investigating a sex crime claim involving a young boy.

The veteran star voluntarily met members of South Yorkshire Police at their premises, and was not arrested or charged.

"The man was interviewed under caution but was not arrested. He entered South Yorkshire Police premises by arrangement."

The singer's Berkshire apartment was searched by police last week as part of the investigation into an alleged sexual assault at a religious event in 1985.

A spokesman for Sir Cliff said on Saturday: "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."

Sir Cliff was in Portugal when the search took place on August 14.

His fans have rallied round the 73-year-old star and are showing their support by buying copies of his 1992 Number Seven hit I Still Believe In You.

The BBC has been accused of a "cover-up" over its role in the raid by officers from South Yorkshire and Thames Valley police.
