A close friend of the fourth celebrity quizzed by the Jimmy Savile probe squad yesterday accused police of indiscriminately rounding up suspects.
He insisted the children’s TV presenter, who is in his 80s, had done nothing wrong.
His backing came as a source close to the Operation Yewtree abuse investigation revealed the elderly star was “almost suicidal”.
The TV host’s mate, who has known him for 50 years, fumed: “Is everyone who ever worked with that man Savile going to be hauled in?
He is being tainted with guilt by association.
“Quite frankly, I think the police should be ashamed of what they’re doing. He wouldn’t do anything like this.
"We’ve spent hours on the river together and in each other’s homes, and we often confide in each other.”
The children’s TV presenter, who we cannot name for legal reasons, was questioned under caution on suspicion of sexual offences at a South London police station on Thursday.
He was released without charge after five hours.
