Donna Hudson, formerly of Rossington, near Doncaster, escaped a jail sentence yesterday despite admitting she made the indecent video and downloading child porn.

The case at Sheffield Crown Court bore disturbing similarities to that of paedophile Vanessa George, of Plymouth, who yesterday gave detectives the names of 10 of her victims.

It is thought nursery worker George, 39, met two other child sex offenders on the internet.

A judge was told yesterday that Hudson's computer revealed she had accessed child porn chatrooms and held images of child pornography. Her mobile phone was found to contain a video of a three-year-old girl simulating sex with a Bob the Builder toy.

Hudson, 33, was driven out of her home by vigilantes after her arrest and yesterday Judge John Bullimore banned her from Doncaster, saying: "People have been disgusted and offended by learning what happened."

Peter Pimm, prosecuting, said the mobile phone footage was uncovered on May 16, 2007.

A week later Hudson voluntarily went to the police and said she had done it "as a laugh" and did not instruct or encourage the child.

Further investigations revealed a large number of video recordings of child pornography downloaded in 2005 and 2006 on her computer, some next to the highest level of seriousness.

Transcripts of conversations she had in internet chatrooms showed she had chatted to a man in Wolverhampton who had been convicted of making indecent images of children and she had revealed an interest in child porn.

She referred to having sex with her boyfriend in front of the the three-year-old girl and sharing child porn files with the man.

Hudson, formerly of Boswell Close, Rossington, Doncaster later said the images must have been downloaded by her ex-boyfriend but he denied it.

She admitted making an indecent film of a child and four offences of making indecent images of children.

Another eight offences of making indecent images of children were allowed to lie on file.

Ian Groom, defending, said Hudson had a sad personal history and was "clearly vulnerable." He said she had been trawling the internet looking for relationships which led her into the offences.

The court heard she had to leave Rossington following her arrest and an arson attack by vigilantes looking for her led to a fire at a different house forcing a family of five to flee for their lives.

Judge Bullimore gave Hudson a 22-week prison term suspended for two years.

She was made subject to a Sex Offenders' Prevention Order, banned from entering Doncaster for at least six months except for supervised visits with social services, and barred from working with children indefinitely.
