British entertainer Cliff Richard has been re-interviewed by South Yorkshire police after agreeing to meet the police officers voluntarily over sexual assault allegations. He was interviewed under caution last year by detectives investigating allegations of sexual assault.

Richard's spokesman confirmed this saying: "Sir Cliff Richard voluntarily met with and was interviewed by members of South Yorkshire Police. He was not arrested or charged, nor has he ever been. He co-operated with officers and answered the questions put to him."

The spokesman said the singer spoke to the police officers this week. "Other than restating that the allegations are 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."

Earlier this year, South Yorkshire Police Chief Constable David Crompton said that its investigation had "increased significantly in size" and involved "more than one allegation." He was unable to say when the investigations will be concluded due to the "expanding nature" of the probe.

Crompton's letter to Keith Vaz, the chairman of the Commons Home Affairs Select Committee was published by the committee, drawing the ire of Cliff's legal team who said the disclosure had caused him a "further round of unnecessary and extremely damaging media coverage."

The 75-year old singer has denied the allegations saying that the claims were "absurd and untrue." It is not known what police questioned Richard about.
