A TEENAGE girl would still be being abused by a former college tutor from Grove if his crimes had not been discovered by police in Germany, an Abingdon detective said last night.

Freemason Ian Holden “embarked on a campaign of grooming” – filming himself having sex with a young girl before posting indecent photographs of her on the internet during a four-year period of abuse.

However he also posted what were described as ‘low-level’ images of another child online, which German police discovered along with the 63-year-old’s IP address.

They then handed over the case to their British counterparts.

When Holden was arrested they also uncovered the footage of him abusing his victim, starting when she was 10 years old.

Dc John Ablett, of Abingdon CID, said without the report of the first indecent image “she would still be being abused. I have no doubt about that.”

Holden was jailed for 12 years at Oxford Crown Court on Friday after admitting a total of 19 charges.

The court heard he would sometimes tell his victim he would buy her a McDonalds meal if he could have sex with her.

Judge Patrick Eccles was shown some of the 20 minutes of footage Holden had secretly recorded as he abused the girl on three separate occasions.

Prosecutor Cathy Olliver said “words are not equal to describe” the acts shown on the clips.

Miss Olliver, who said the girl had been abused between 2006 and 2011, told the court: “Mr Holden embarked on a campaign of grooming her.”

She added the victim, who is now aware that two indecent pictures of her were posted online on three occasions, “felt like she wanted to end her life and that she was worthless. She started cutting herself due to the sense of worthlessness she felt”.

Miss Olliver continued: “She says she tries to put a smile on her face, she tries not to be sad these days but it’s hard not to be sad.”

Holden admitted seven counts of engaging in sexual activity with a child, one of a serious sexual assault on a girl under 13 and 11 counts of distributing indecent images of children.

Jonathan Clarke, defending, said his client had a “history of having been a victim of sexual abuse himself as a child”.

Judge Eccles also placed Holden on an extended licence period of 10 years upon his release.

He called the behaviour a “truly shocking array of sexual offences” and said Holden had a “deeply deviant and entrenched obsession with images of children”.

Principal of the Oxford Business College David Fogg said Holden had worked part time for the college as a tutor, but had not done so for more than two years.
