A teenager locked up for right-wing terror offences has been sentenced over possessing indecent images of children and extreme pornography, Scotland Yard said.
Jacek Tchorzewski, 19, was caught with a range of documents for planning an attack when his electronics were seized at Luton Airport in February of last year.
The Metropolitan Police said that, as well as a number of documents breaching the Terrorism Act 200, he was also found to be in possession of indecent images.
Four of the images were classified Category A, the most serious type, and a further eight were classified Category B and C, the force said.
Tchorzewski, of High Wycombe, Buckinghamshire, pleaded guilty to three counts of possessing indecent images of children and one count of possessing extreme pornographic images on June 8, according to police.
Police said that he was sentenced to eight months’ imprisonment at Harrow Crown Court on Wednesday, to run concurrently with his four-year sentence for terrorism offences.
The Polish national is also subject to a deportation order, meaning he will be deported from the UK when he has served his time in custody, police added.
Tchorzewski was sentenced to four years behind bars at the Old Bailey in September, after pleading guilty to 10 counts of possession of documents containing information of use to a terrorist at an earlier date.
Officers stopped the 19-year-old at Luton Airport on February 20 2019, where he was searched and his mobile phone was seized.
The investigation found that Tchorzewski had downloaded right-wing material which which praised Hitler and Satanism, and he had amassed guides on terrorism, bomb-making and gun production.
Following the sentencing on Wednesday, Commander Richard Smith, head of the Met Police Counter Terrorism Command, said: “Tchorzewski had some of the most severe types of images on his phone.
“We and our counter terrorism police network colleagues treated these crimes with the focus and seriousness they deserved, ensuring Tchorzewski faced justice for these offences as well as his terrorist activity.
“Right-wing cases increasingly account for the overall number of counter terrorism investigations nationally and we are seeing more people of extreme right-wing mindset referred to Prevent.
“I urge anyone with concerns that an individual may be involved in right-wing terrorist activity or child sexual abuse to report their concerns to police.”
