Gary Glitter, a pedophile, was called to prison after he was recorded looking at footage of young girls dancing ballet.
The 78-year-old will have to spend at least another full year in jail as he was caught looking at the footage on YouTube and TikTok.
The pervert was looking at girls as young as eight years old in leotards and short skirts as they performed in ballet performances and gymnastics routines.
Checks on his phone found that he had also downloaded and deleted an app called DuckDuckGo, which could give access to the dark web.
Glitter, whose real name is Paul Gad, said he only watched the videos because he was interested in the performing arts.

The sick pervert was looking at girls as young as eight in leotards and miniskirts as they performed in ballet performances and gymnastics routines.
However, parole officers thought it showed a pedophile might still lust after young girls, The Sun reported.
In February, Glitter was released from HMP The Verne in Dorset after serving half of his 18-year sentence for the abuse of three girls in the 1970s.
After just 38 days Glitter was recalled to prison in March and is now in HMP The Verne prison in Dorset.
It will be at least a year before he can apply for parole again, which means the aging former rock star could die in prison.
When the 78-year-old was released in February, he was halfway through his 16-year prison sentence for sexually assaulting three schoolgirls.
He was at the height of his fame when he took advantage of his victims, who thought no one would believe their claims because of his celebrity status.
The crimes came to light almost 40 years later, when Glitter became the first person to be arrested under Operation Yewtree – the investigation launched by the Metropolitan Police in the wake of the Jimmy Savile scandal.
His fall from grace occurred years earlier, after he admitted possession of 4,000 images of child pornography and was jailed for four months in 1999.
A Ministry of Justice spokesperson said: “The Deputy Prime Minister will do everything he can to keep dangerous criminals like Paul Gad behind bars and tighten the parole system to keep the public safe.”
It came as former head of Scotland Yard’s pedophilia unit, Mike Hammes, said disgraced ’70s pop star Glitter would always be a danger to children and that a return to foster care was appropriate.
Speaking to the Radio Times, Mr Hamees said Glitter “wasn’t allowed to do certain things on his phone”.

He added, “As far as Jad is concerned, he’s so dangerous and so focused on his abusive behavior that he’ll never stop – he’s gone too far. He’s arrogant, and he’s stubborn.”
“He’s someone who will always be a danger to kids, quite frankly.”
Asked about Glitter’s recent return to prison, Mr. Hamees said: “(I have) no doubt that he will serve the next eight years of his sentence…he will probably die in prison.”
Glitter is released on bail with six other convicted paedophiles, and it was revealed after the former pop star was called to jail for violating the terms of his license.
Glitter was ordered back to jail on March 13, after he was secretly filmed browsing a smartphone and pointing to the dark web just a month after his release.
He was staying in a hostel in the south of England with six other pedophiles who had been released on licence.

The disgraced pop star (pictured in 1972) was jailed in 2015 for sexually assaulting three young girls in the 1970s.
Glitter was previously filmed appearing to discuss how to access the Dark Web with fellow lodge residents, in footage he obtained the sun.
Pictured wearing a black beanie and hoodie, the convicted child molester stares at a smartphone while he talks to others in the room.
He says, “Should I get rid of this duckling?”
Another guy says, “Yeah, I wouldn’t bother using this if I were you.”
Glitter adds: ‘So what do I do next? Let’s try to find this onion. One step at a time.’
It is understood that “Duck duck” refers to DuckDuckGo, a search engine that protects users’ privacy, while “Onion” is believed to be a reference to the Dark Web.
Pedophiles often use the dark web to access child sexual material.
The secret footage of Glitter is sent to the surveillance service, which lands him back in jail.
Police are checking the phone to assess whether the disgraced pop star used the dark web after being released on licence.
