'The operation has three strands.

One is looking specifically at the actions of Jimmy Savile and the second strand concerns allegations against "Savile and others". The separate third strand relates to alleged complaints against other people unconnected to the Jimmy Savile investigations.

Scotland Yard said the man they took to a central London police station on Thursday morning was being investigated under the last strand of Yewtree's investigations.'
