Comedian Jimmy Tarbuck has been arrested in connection with a historical child sex abuse investigation in Harrogate, the BBC understands.
North Yorkshire Police confirmed that a 73-year-old man was arrested in Kingston upon Thames on 26 April.
The entertainer and quiz show host was released on police bail pending further enquiries.
The complaint relates to an alleged incident in the late 1970s.
North Yorkshire Police says Mr Tarbuck's arrest came after information was passed on by Metropolitan Police officers working on Operation Yewtree.
The force stressed that this arrest "is not part of Yewtree, but a separate investigation" by North Yorkshire Police.
Operation Yewtree was set up following the death of Jimmy Savile in 2011, when hundreds of sex abuse allegations came to light about the former DJ.
