Jimmy Savile has been filmed groping a teenage girl in front of camera filming for his documentary.
Investigative journalist and BBC film-maker Louis Theroux, 46, saw Jhim rubbing himself against her and touching her bottom.
What’s even more disturbing is that she was with her mother, whom he apparently knew.
Both Louis and Jimmy are then seen laughing and joking around with each other as they leave the Flying Pizzza restaurant in Leeds.
The camera footage is being shown for the first time, 16 years after Louis Theroux tried to expose him in the documentary When Louis Met Jimmy.
The father-of-three says now that he developed “something like a friendship” with Savile, who has supposedly abused 1,000 victims over six decades.
Louis, who is a BAFTA-winning filmmaker describes the disturbing moment as “uncomfortable viewing”.
The all-telling doc that is called Louis Theroux: Savile is on tomorrow night on BBC2, sees that victims called the presenter “gullible” for failing to spot that Savile was a paedophile.
One of them said: “To me, it was obvious.”
Louis replied: “It’s like quizzes, it’s only obviously because you know the answer.”
Back in 2001 Theroux reported Savile after he confessed he had slept with a 15-year-old girl.
But a BBC producer chose not to tell the police.
