THE police investigation into veteran singer Sir Cliff Richard has "increased significantly in size" and involves "more than one allegation", South Yorkshire's chief constable has revealed.
David Crompton said the "expanding nature" of the investigation meant he could not give a date when it would be concluded.
Sir Cliff said the claims against him were "absurd and untrue" and he had "never, in my life, assaulted anyone".
The entertainer was interviewed under caution last year by detectives investigating a claim of a sex crime involving a young boy in the 1980s, but was not arrested or charged.
In a letter to Keith Vaz, chairman of the Commons Home Affairs Select Committee, Mr Crompton said the force was in regular contact with Sir Cliff's lawyers.
But in a statement the 74-year-old singer said he had not been given details of the allegations against him.
