A Norfolk man who forced American teenage girls to send him degrading images of themselves posing as his ‘sex slaves’ has been jailed for 10 years.

Jack Brennan, 29, groomed a 15-year-old and 13-year-old from Montana and Oregon who he befriended on Snapchat, encouraging them to send him naked photographs of themselves.

He then threatened to post the pictures in Facebook groups and send them to their parents unless they indulged his depraved fantasies. 

One was told she would be taken into foster care if she spoke out.

 Another was threatened with paedophiles being sent to the home of a six-year-old relative unless she continued to send ever more degrading videos and pictures.

Jailing him for a total of 10 years at Norwich Crown Court, Recorder John Hardy said he had forced them into a form of “sexual enslavement”.

Prosecutor Lori Tucker said Brennan, of Estcourt Road in Attleborough, told the girls to only refer to him as “daddy” and “master”. 

Under the threats of having naked images exposed they were forced to send pictures of themselves in sexual acts with degrading explicit words written on their faces and bodies.

One had been threatened into sending him a video of herself licking a toilet seat, said Ms Tucker.

A third girl aged 11, from Texas, was also lured into sending naked pictures.

Police were alerted by US Homeland Security after a victim’s boyfriend disclosed to local law enforcement offices that Brennan had contacted them.

Investigations into Brennan’s Snapchat account identified further victims.

More than 100 child sex videos and almost a thousand indecent photos of children were also found in a file on his phone after he was arrested in the UK.

At the time Brennan was already subject to sexual offending restrictions following a conviction for possession of indecent images of children in 2019.

He continued to target the American youngsters despite being under investigation for offences, the court was told.  

He pleaded guilty to three counts of possession of indecent photographs of a child, two counts of sexual communication with a child between November 2021 and February 2022.

He also admitted two counts of causing a child to engage in sexual activity, distributing indecent photographs of a child and of failing to comply with an earlier 10-year sexual offending order.

Recorder John Hardy told him he had carried out “repugnant and repulsive aspects of degradation, abuse and enslavement of these young girls, who were children and whose childhood you defiled”.

He ordered that he sign the sex offenders’ register and issued a sexual harm prevention order that includes a ban from travelling to the US for five years.

Brennan was told he will have to serve at least two-thirds of his sentence in prison.

Speaking after the sentencing, Detective Constable Kat Baldwin said: "This case involved the predatory sexual behaviour of an adult over children.

“These offences can often leave a mark on their victim for the rest of their lives, so I am pleased to see this case has now come to a positive conclusion.”

Detective Sergeant Pete Wilson said: "The sentence passed by the court reflects the severity of the defendant's actions and the threat that he poses and will ensure that the victims and public will remain safe from this individual in the future.

“We hope the court case will help to bring some closure for the victims and their families."
