Prosecutor Sharon Bahia said the defendant was jailed for three years in 2017 for meeting a child following sexual grooming, sexual activity with a child, attempting to meet a child following sexual grooming and possessing extreme pornography.
He was made the subject of a SHPO until further order which prohibited him from contacting girls under 16.
But Charlesworth contacted three ’14-year-old girls’ who were in fact decoys ‘.
Miss Bahia said: “He made contact with one. She said she was 14. The defendant continued to chat with her, telling her he was 20. He quickly steered the chat into a sexual nature.
“He referred to the ‘kissable’ lips she had and asked if she had ever been kissed. He asked if she wanted a spanking
The second ‘girl’ was also 14. Miss Bahia said: “He asked her to put her hand in her underwear and rub between her legs. He asked how it felt.”
He also talked sexually to a third decoy, who also claimed to be 14.
The final decoy was a 28-year-old woman and they arranged to meet at Hanley’s Central Forest Park at 2pm on June 11.
Miss Bahia said: “The paedophile hunter group produced a number of chat logs of evidence. There were hundreds of pages of messages with all three decoys.
“His phone was seized. He was allowed to leave but he was formally arrested the next day.”
Charlesworth, of Vale Street, Stoke, pleaded guilty to three charges of attempting to breach a Sexual Harm Prevention Order (SHPO), three offences of attempting to engage in sexual communication, and attempting to incite a child to engage in non-penetrative sexual activity.
Judge Paul Glenn made Charlesworth the subject of a new SHPO which will run indefinitely. He will also be on the sex offenders’ register indefinitely and was barred from activities involving children and vulnerable adults.
Judge Glenn said: “You used a profile showing a picture of Steve McGarrett, a character in Hawaii Five-O.
“You were communicating with adult members of a paedophile hunter group, rather than three teenage girls you thought you were communicating with. You sent hundreds of messages plainly trying to groom those children which you thought they were.”
The judge said it was ‘quite disgusting material’. He added: “I am conscious all these matters were attempts. There were in fact no victims. There was in fact no actual harm.
“I am satisfied you represent a significant risk of serious harm to members of the public by the commission of further specified offences. You represent a risk to young females under 16.”
