A pervert who molested young girls after contacting them on Facebook and made vile suggestions has been branded a danger and locked up for public protection.

Sean Medland was jailed for nine years and will be on licence for a further five years. He will have to serve two thirds of the sentence before the parole board will consider his release.

The 24-year-old father sobbed while handcuffed in the dock as a judge told him he had carried out “an organised, deliberate and planned course of conduct” involving four girls.

Using aliases such as Yip Yip Dibble, Kriss Kross, and Billy Baker, and using a profile picture of a muscly body on Facebook, Medland contacted one girl, aged 15, in Sittingbourne.

He sent her a message saying: “Hey beautiful, do you want to earn some money?”

When she replied, he said he would give her “a couple of grand” if she would perform a perverse and degrading act on him.

“On one occasion he asked her to send a dirty picture of herself, but she didn’t,” prosecutor Danny Moore told a jury at Maidstone Crown Court in November.

The girl blocked him on Facebook. But after she turned 16 in 2012, he contacted her again and agreed to go to Sheerness with him. He bought her a meal at McDonald’s.

She met him again and they went to the cinema in Maidstone. During the film he sexually assaulted her and she pushed him away.

They then went to a hotel in Ashford. Again, he molested her and made the same lewd request.

Medland contacted the girl’s mother and claimed he was a police officer working in the firearms unit.

He also tried to groom other girls, offering them money to perform the same act on him.

He met one girl, aged 14, in Sheerness and went to a hotel and had intercourse with her.

She later told police she tried to push him off but he just carried on.

Medland, of Hurst Road, Bexley, denied five charges of inciting a child to engage in sexual activity and one of sexual activity with a child, but was convicted.

His name will appear on the sex offenders’ register indefinitely and he will be barred from working with children and vulnerable adults.

Judge Julian Smith said Medland had to be sentenced for misconduct directed at four girls all under the age of 16 between 2012 and 2014.

“You continue to deny any wrongdoing and maintain that you had been a victim of a conspiracy orchestrated by your former partner,” he said.

“You maintained you would only undertake courses to prove your innocence. Your mother remains staunch in her support of you.

“The dominant feature is your mental disorder. I accept you have to deal with it on a daily basis.”

Medland had previously been sentenced for fraud in which he posed as a photographer for FHM magazine and persuaded women to send him intimate pictures.

He had sought to manipulate and control young girls to further his cause.

Medland told one girl he wanted to have sex with her and said he would buy her sexy underwear for her 13th birthday. He wanted her to wear her school uniform.

“You were convicted on overwhelming evidence,” said the judge. “There is clearly no hint of remorse or insight in your mind. These are serious offences indeed.

“They are made more sinister by threatening and intimidating, using the false identity of a police officer.”

Judge Smith added: “I take the view you are a danger and pass a sentence to address that.”
