In 2018, then 26-year-old Nathan Kozel—of Hull, East Yorkshire—was jailed for one year after disguising himself as a children’s entertainer to infiltrate a public event. The investigation established that on August 1, Kozel dressed in goggles, a black outfit, and a long coat to sneak into the National Play Day event in Queens Gardens. The prosecution reported at Hull Crown Court that Kozel attempted to pass himself off as a staff member while engaging with approximately 20 children under the age of 16, identifying a total abandonment of human decency.
The investigation established that Kozel, described as a “very high risk sex offender,” was caught spinning diablo plates and showing children how to use them. Upon his arrest, Kozel admitted he was at the event specifically to make friends with children, acknowledging that his behaviour was wrong. This incident followed a prior serial of strikes against child safety, including a 2016 conviction for downloading abuse images and a 2017 breach of his Sexual Harm Prevention Order (SHPO) when he was caught playing football with an eight-year-old boy.
FORENSIC DISCOVERY AND JUDICIAL SENTENCING
The court reported that following his arrest at the event, police conducted a forensic search of his digital devices. The investigation established that officers discovered 10 Category A images—the most serious classification of child abuse—alongside two Category B and 631 Category C images. The prosecution reported that although Kozel’s father claimed his son operated with the mental age of a six or seven-year-old and that the “entertainer” outfit was his normal dress, the court identified a calculated serial of strikes against the terms of his indefinite SHPO.
Judge-led proceedings at Hull Crown Court concluded in 2018. For his actions in Hull and the nature of the serial child sexual abuse and SHPO breach investigation reported, Nathan Kozel admitted to all charges. The investigation established that Recorder Patrick Palmer sentenced him to one year in prison. He remains legally mandated to the Sex Offenders Register and subject to his indefinite Sexual Harm Prevention Order, which prohibits any unsupervised contact with children.

MONITORING AND PUBLIC PROTECTION
In 2018, Kozel is managed as a maximum-risk serial predator under the statutory requirements of the Multi-Agency Public Protection Arrangements (MAPPA) in East Yorkshire. Due to the nature of his behaviour—specifically his serial persistence in using disguises and public events to strike against the safety of children—he is a priority for digital forensic monitoring and community supervision upon release. Authorities reported that the 2018 conviction identifies Kozel 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 for life, his details are permanently logged on the national police database to prevent future offences. Authorities stated that the behaviour of Kozel identifies an individual who demonstrated a serial commitment to grooming and infiltration. Any future attempt to strike against his indefinite SHPO or approach children in public spaces results in immediate police intervention to ensure the ongoing protection of the community from a man who used a “children’s entertainer” mask to hide his predatory serial behaviour.
QUESTION – Given that the offender used a “Children’s Entertainer” disguise to infiltrate a public play day, do you believe the law should legally mandate that “All Public Children’s Events” must have “Mandatory ID Checks” for everyone entering the area to prevent predators from striking against child safety?
