A member of an internationally-renowned parkour supergroup has pleaded guilty to making and possessing nearly 3,000 indecent images of children.
Callum Powell, 34, spent over a decade as part of Storror, a team of seven professional freerunners who post their weekly adventures on YouTube.
The group has more than 11 million subscribers on the popular streaming platform and has appeared in two films by Transformers director Michael Bay.
Powell appeared at Brighton Magistrates' Court on May 7, where he pleaded guilty to three charges of making indecent photographs or pseudo-photographs of a child, one charge of possessing a prohibited image of a child, and one charge of possessing extreme pornographic images portraying a sex act with an animal.
In total, he was charged with making or possessing 2,649 category C, 105 category B and 178 category A indecent images or pseudo-images of children.
Category C images are those depicting children in non-sex acts but which remain illegal under UK indecency laws.
Category B are images showing non-penetrative sexual activity, while Category A images depict children subjected to penetrative sexual activity, bestiality or sexual activity involving sadism.
'Pseudo-images', which include AI generated content, are defined by the Protection of Children Act 1978 as 'an image, whether made by computer-graphics or otherwise howsoever, which appears to be a photograph'.

The disgraced parkour athlete was released on bail, on the condition that he is not to live in the same household, or have contact or communication, with a child under 18.
He is also prohibited from using any computer or device capable of accessing the internet, or possessing any device capable of storing digital images, moving or still.
The judge adjourned the case while a pre-sentence report is carried out. The next hearing is set for July 10, 2026, when Powell is due to be sentenced at Brighton Magistrates' Court.
In a statement posted on Instagram, Storror said that Powell had been removed from the group 'with immediate effect' upon learning of his offending.
'On 7th May the STORROR team was made aware that Callum Powell had pleaded guilty to offences related to making and possession of indecent images of children,' they wrote.
'Prior to this the team was unaware that Callum had faced these charges. These offences are appalling, and the team is profoundly shocked and distressed.
'STORROR's work has always been built on inspiring young people. The conduct that Callum has admitted to is a betrayal of that, and of the trust placed in him by this team and our audience.
'Callum has been removed from STORROR with immediate effect and is no longer involved with the company in any capacity.
'Our of respect for the ongoing legal proceedings, we will not comment further at this stage.'
Powell has been part of Storror since 2010. The team attracted legions of fans globally with footage of daring parkour stunts, often performed on rooftops at altitude.
In 2017, Storror's self-shot film Roof Culture Asia won them a new influx of supporters after showcasing them jumping between skyscrapers in Hong Kong, Tokyo and Seoul.
Having performed stunts in Michael Bay's 2019 Netflix film '6 Underground', the Hollywood director returned to the group for an in-depth profile with 2025's 'We Are Storror' - although the documentary has yet to be released commercially in the UK.

While none of the individual members of Storror have so far commented publicly on Powell's guilty plea, several people in the group's wider orbit have addressed his offending.
Professional parkour athlete Hazal Nehir, who is the wife of Storror member Benj Cave and sometimes appears in the group's videos, posted footage of her burning Powell's 2026 book 'What Is Parkour? - The Sport With an Identity Crisis'.
Joe Williams, another Brighton-based parkour athlete, also took to Instagram, describing himself and the community as 'horrified, disgusted and in shock' - in a message reposted by Storror's official cameraman, Jack Dodds.
'Me and those in the Brighton community are horrified, disgusted and in shock. Thoughts are of course with any victims or people directly affected by this,' Williams wrote.
'It's important to remember that he was clearly very good at hiding this side of his personality, as I've seen other people say they never suspected anything and this goes for us in the Brighton community too.
'We've always taken pride in our community here being open and against this kind of behaviour, which makes it all the more heartbreaking to find out this behaviour has in fact been happening within our community.'
Storror are renowned for posting a new video every Monday but have not uploaded anything since the news of Powell's guilty plea broke.
The group have also taken down more than a third video library. The Wayback Machine shows that at the start of last week they had more than 1,200 videos on their site, but only 744 remain - with the vast majority accessible to members only.
It is not yet clear if the videos that have been taken down are going to be re-edited to remove Powell or if they have been permanently deleted. The group have also removed all the episodes of their podcast.
'Parkour UK is appalled by the offences admitted by Callum Powell,' the sport's governing body said in a statement.
'There can be no such place for this abhorrent behaviour, and our thoughts are with all those affected.
'While Callum Powell has no affiliation with Parkour UK, we know this news is deeply upsetting for many people across our community. It is a stark reminder of the importance of constant vigilance and continued action around safeguarding for all those associated with our sport.'
Storror declined to comment further at this stage.
