A “DANGEROUS” paedophile who preys on underage girls swore at the judge who jailed him and swung a chair towards prison officers during an angry outburst.

The prison videolink from HMP Hewell was cut abruptly when sex offender Jonathon Blackwell, who had kissed and groped a girl of 14, threw a tantrum in the prison booth.

The 24-year-old, who has learning difficulties, shouted and struggled with prison officers when jailed by judge Robert Juckes QC at Worcester Crown Court on Monday.

Throughout the hearing Blackwell could be seen on a large screen in the court slumped forward while he sat at the table in the booth. His head was placed on his folded arms and at one point he laughed as he tapped the microphone.

But Blackwell’s jocular mood changed when the judge handed him an extended sentence because he was deemed a danger to young girls.

Blackwell, previously of Elizabeth Avenue, Droitwich, swore at the judge, shouted ‘it was only a touch!’ and ‘I’m not doing that long for that!’

He picked up a chair and swung it at prison officers and at one stage tried to pick up the table but was unable to do so because the tables in the prison’s videolink rooms are fixed to the floor.

Blackwell admitted sexual touching against a 14-year-old girl which he committed in April this year, waiting until there were no adults in the room before carrying out the assault.

Michael Hall, prosecuting, described the offence as ‘opportunist touching’ with Blackwell sitting her on his knee and lap once adults had left the room.

The girl described how Blackwell ‘put her on his lap and snogged her neck’, touched her under her jumper and touched her bottom and private parts over her clothing.

Mr Hall told the court: “She moved his hand away and that brought a response from Mr Blackwell, saying ‘you know you love me’.”

When he had finished touching her, Mr Hall said Blackwell ‘would put her back as if nothing had happened’ before any adults came back into the room.

Blackwell was previously convicted of four offences of sexual activity with a female child under 16 on August 18, 2014. Mr Hall said the offences involved penetration.

Blackwell received a 24 month suspended sentence suspended for two years for these offences which took place between 2011 and 2013 when Blackwell was aged between 16 and 18. The three girls in question were aged 12 to 14 years at the time, Blackwell making contact with them through Facebook or through associates at a school, the court heard.

Mr Hall said of the third complainant: “He had invited her to his home address and pinned her against a wall and tried to kiss her.”

Blackwell was jailed for three years in the early part of 2015 after the two year suspended sentence was activated and he received a further 12 months imposed consecutively for meeting a girl following sexual grooming and breach of a sexual harm prevention order.

Blackwell had contacted a girl aged 13 on the internet and sent her texts before meeting her ‘with the intention of engaging in sexual activity’.

He had been due for release on licence in August 2016 but served the entirety of his sentence.

Mr Hall said: “He made threats to kill his probation officer. He was then arrested at the prison gates on release.”

Blackwell was convicted of two offences of assaulting a constable and using threatening or abusive behaviour. He was released from prison on February 21 this year before his arrest for the sexual assault on the 14-year-old.

Mr Hall argued that the latest offence was aggravated by the defendant’s previous convictions.

Jason Aris, defending, said because of his client’s emotional immaturity he identified with younger females and described him as ‘presenting as a very young looking man.’

Mr Aris said the custodial environment had provided him with structure but added: “The concern is that he will become institutionalised at a young age. He finds living in the community significantly more stressful than living in a prison setting.”

Judge Juckes said Blackwell had shown by his behaviour that he could not be trusted in the presence of young girls, describing the offence as ‘serious’.

He said: “You represent an obvious and ongoing risk of danger to children in the community.”

The judge jailed him for 26 months but added an extended licence period of five years, making a total licence period of seven years and two months.

He will not be eligible for release until he has served two thirds of the 26 months and even then will not be released until it it is deemed safe to do so.

Blackwell remains subject to a sexual harm prevention order which has been amended as part of this sentence.
