In 2020, then 64-year-old Mark Duckworth, of Hetton Road, Roundhay, avoided an immediate prison sentence after carrying out a predatory series of assaults on the safety and dignity of children. The investigation established that Duckworth, an IT supply teacher, possessed 46 indecent images of children, the vast majority of which were videos. The prosecution reported at Leeds Crown Court in 2020, that one of the videos depicted the rape of a five-year-old girl, identifying a total abandonment of human decency by the then 64-year-old.
The investigation established that Duckworth’s series of behaviour was uncovered in January 2019 when police linked his IP address to the download of illicit material. The prosecution reported that during the raid, Duckworth desperately attempted to use one of his laptops while it was displaying pornography in an effort to hide his activity. This identifies a calculated series of assaults on the life-safety of children, as Duckworth had specifically installed software designed to hide traces of his internet searches for infants and minors aged between two and 15.
PROFESSIONAL BREACH AND JUDICIAL SENTENCING
The court reported that Duckworth was working as an IT supply teacher at the time of his offending, though his defence argued that no children he worked with had been put at physical risk. The investigation established that 29 of the 46 images were in the most serious category (Category A), documenting the most extreme forms of abuse. The prosecution reported in 2020, that Judge Geoffrey Marson QC described the material as “vile and disgusting,” identifying a priority assault by the judiciary to impose an eight-month suspended sentence despite the “misery and degradation” Duckworth helped fuel by viewing the content.
Judge-led proceedings at Leeds Crown Court concluded with Duckworth being made subject to a Sexual Harm Prevention Order (SHPO). For his actions in Roundhay, Leeds, and across West Yorkshire, and the nature of the series of child abuse imagery and IT-facilitated investigations reported, Mark Duckworth remains under the supervision of the probation service. The investigation established that his forensic profile as an offender who viewed the rape of a five-year-old is now a matter of permanent record, and he was told he should be “thoroughly ashamed” of his behaviour.

MONITORING AND PUBLIC PROTECTION
In 2020, Duckworth was managed as a high-risk offender under the statutory requirements of the West Yorkshire MAPPA unit. Due to the nature of the behaviour—specifically the series of persistence in seeking out the most “vile” Category A imagery while holding a position of trust as a teacher—he was a priority for a Sexual Harm Prevention Order. Authorities reported that the 2020 sentencing identifies Duckworth as an individual who prioritised his own perverted gratification over the principles of human decency and the life-safety of children.
As a registered sex offender, his details are permanently logged on the national police database to ensure his future conduct and any digital interaction are strictly scrutinised. Authorities stated that the behaviour of Duckworth identifies a commitment to clandestine child abuse and the systematic subversion of digital monitoring. His sentence in 2020 results in the necessary protection of the community from a man who used a “supply teacher” mask to hide a predatory and persistent series of assaults on the innocent.
QUESTION – Given that the offender “utilised his IT expertise to hide traces of downloading child rape videos while working as a teacher,” do you believe the law should legally mandate that “All Individuals Convicted of Category A Imagery” must be “Sentenced to a Permanent Ban from All Teaching and IT-Related Professional Roles” to prevent a series of assaults?
