A SEX offender told an undercover police officer, posing on a dating app, that he was a ‘genuine paedophile’.

Leonard Vandervail confessed his sexual interest in children on a dating app and bragged that the youngest he had abused was four years old.

The 43-year-old thought he was messaging a woman, aged 22, with three children on the app but was speaking to an undercover police officer.

Prosecutor Rod Blain told Bournemouth Crown Court on March 7 that Vandervail told the woman he was looking for a little girl.

After saying she had three children, the undercover police officer asked the defendant if he wanted to meet them, and he said yes.

They began messaging on another messaging platform where the defendant ‘wasted no time’ in asking how old the children were.

She told Vandervail that her two ‘daughters’ and ‘son’ were aged 10, two and seven.

The defendant then admitted his sexual interest in their ages, saying the youngest he had abused was four years old.

He said that this happened regularly and ‘assured’ her that he was a ‘genuine paedophile’.

When asked if anything was off limits, he said he would do anything.

After confessing further details of ‘activities’, Vandervail and the woman arranged to meet her ‘children’.

The defendant said he was from Bournemouth and sent a picture of himself, which police were able to use to identify him.

Dorset Police then confirmed that Vandervail was already a known sex offender and had previously been given a sexual harm prevention order.

Mitigating, Nick Robinson said that the harm made was to a fictitious child and that according to the defendant, the comments made were fantasy whilst under the influence of drink and cannabis.

Mr Robinson said that Vandervail completed the sex offender programme eight months ago and ‘did very well’, but has regressed to previous behaviour.

He added that the defendant is sorry and is keen to engage with probation to reduce the risk of this happening again.

Vandervail, of Wootton Mount in Bournemouth, was charged with three counts of making indecent photograph/ pseudo-photograph of a child and breaching a sexual harm prevention order.

His Honour Judge Robert Pawson said the defendant has a ‘very troubling’ history that is rooted in sexual attraction to children which goes back over 10 years.

Vandervail was sentenced to three years in prison, given a sexual harm prevention order indefinitely and put on the sex offender register for life.

A spokesperson from Dorset Police's POLIT team (Paedophile On-Line Investigation Team) said: “The POLIT team is committed to working with partners such as the National Crime Agency, other police forces and a wide range of other agencies and organisations to minimise the risk to children by proactively identifying people who use the internet to further their sexual abuse in children.

“We urge anyone to contact Dorset Police or Crimestoppers if they suspect someone is using the internet to groom or gain indecent images of children.”
