A volunteer Metropolitan Police officer found guilty of raping and sexually assaulting a child may have more victims.
James Bubb, who now identifies as a woman named Gwyn Samuels, faces a lengthy jail sentence after being convicted of a string of sexual offences against the child, as well as raping an adult woman repeatedly for years.
Amersham Law Courts heard Bubb groomed a child online before sexually assaulting her when she was just 12 years old.
He signed up as a Special Constable with the Met in 2020, was a volunteer steward at Christian festivals, and previously worked at the exclusive Harrow private school.
After the convictions on Thursday, detectives said it is a “possibility” that Bubb had more victims who have yet to come forward.
“We keep an open mind as to any other offending committed by this defendant”, said Detective Constable Kirsty Pendle, of Thames Valley Police.
She branded Bubb a “dangerous, predatory sex offender”, and welcomed the guilty verdicts for his “appalling” crimes.
Bubb, 27, was convicted of rape, sexual activity with a child, rape of a child under 13, assault by penetration and assault of a child under 13 by penetration
The defendant, from Chesham in Buckinghamshire was also found guilty of raping a woman he met online while posing as a 16-year-old girl.
He was found not guilty of one count of rape against the child victim and one count of sexual activity with a child.
The offences took place between January 1 2018 and April 2, 2024, in London and Buckinghamshire.
The trial was told that Bubb met his first victim on the online chat site Omegle in 2018 before meeting in person for the first time at a Christian festival a few months later.
The girl said the defendant looked "paranoid" when he was with her, and she was being "hidden" when they were in public together, telling police her festival colour-coded child wristband was clearly on show.
Bubb sexually assaulted the girl in public shortly before her 13th birthday and was forced to pull his trousers up after a dog walker went past him, the court heard.
His first victim also said the defendant spoke "a lot about the powers he had" in his role with the Met as a special constable.
Jurors were told Bubb was violent towards the girl when he raped and sexually abused her in her early teens, with the victim telling police he choked and punched her.
The court also heard the officer raped his second victim, a woman he met when she had just turned 18, while he was in an on-off relationship with her between January 2018 and February 2023.
The victim said Bubb used "BDSM and kink as a way of creating control" over her.
She said the defendant would "use police training techniques" on her , telling police: "The control, the power he got. It sure as hell wasn't consensual."
Bubb, who wore a black cardigan, glasses, and cream shirt, made no expression as the verdicts were read out but sobbed with their head in their hands after the foreman finished speaking.
Judge Jonathan Cooper told jurors: "This has been a very challenging case, I'm sure, for you as individuals."
He said he tells every jury not to speak about the case outside the jury room, but added: "I recognise that's a very big ask when dealing with counts that would be very, very difficult to hear.
"In this case you heard a range of things that may have been familiar to you, that may have been unfamiliar to you, and may have been unwanted."
Jurors reached verdicts after deliberating for six hours and 32 minutes.
Bubb will be sentenced on December 19.
After the verdict, a spokesperson for the NSPCC child protection charity said: "As a special constable, Bubb should have been someone who could be relied on to keep children safe.
"It is now vital that both the victims in this disturbing case receive all the support they need to move forwards with their lives.
"Bubb's actions also highlight once again how tech companies need to be doing much more to make their platforms safe spaces for children and young people when they go online."
The Met said Bubb was suspended when the allegations first emerged, and there had been no previously complaints about his conduct.
Harrow School said: "The safety and wellbeing of our pupils is always our highest priority. We have no reason to believe that they engaged in any misconduct towards pupils or colleagues."
