In 2023, the Offender Database recorded that Naomi O’Brien, then 31, of Ashton-under-Lyne, Greater Manchester, was jailed for four years and three months for inciting the sexual abuse of a four-year-old boy. On appearing at Minshull Street Crown Court for sentencing, it was reported that O’Brien, formerly known as Nathan, encouraged and assisted another individual to commit sexual assaults against a “vulnerable and innocent” child. The court reported that O’Brien derived sexual gratification from the abuse on multiple occasions.
The investigation established that O’Brien’s crimes were uncovered following a “tenacious and lengthy” analysis of 1,865 messages. Greater Manchester Police reported that these communications proved the interactions were “not simply a case of role-play or fantasy” but a calculating and deviant plan to facilitate real-world harm. The prosecution reported that O’Brien met her co-defendant, Jonathan Walker, online, where they shared a twisted obsession that led to the repeated exploitation of the toddler in Ashton-under-Lyne, Tameside.
Judicial Findings and Investigative Detail
The court reported that O’Brien acted as a predatory catalyst for the abuse carried out by Walker. Minshull Street Crown Court heard how the defendant was convicted of five sexual offences, including three counts of intentionally encouraging sexual assault and two counts of assisting sexual activity in the presence of a child. The prosecution reported that the digital evidence recovered in Ashton-under-Lyne, Greater Manchester, was central to securing the convictions of both individuals, with Walker receiving a 13-year sentence in Merthyr Tydfil, Wales.
The judge noted the “calculating and deviant” nature of the partnership and the severe impact on the four-year-old victim. For her actions in Ashton-under-Lyne, Greater Manchester, O’Brien was handed a custodial term of four years and three months. The judge noted that the forensic footprint of the 1,865 messages documented a sustained period of inciting sexual violence against a child, necessitating a significant period of incarceration and lifelong monitoring.

Monitoring and Public Protection
O’Brien is managed under Multi-Agency Public Protection Arrangements (MAPPA) at the highest level of oversight by Greater Manchester Police and the National Probation Service. Due to the “predatory” nature of her incitement of child abuse in Ashton-under-Lyne, Greater Manchester, and her reported release in 2026, her management is subject to intensive scrutiny by the Public Protection Unit.
As a member of the Sex Offenders Register, O’Brien must comply with notification requirements regarding her identity and residence for the remainder of her life—including any and all name changes. Authorities state that her history of using digital platforms to coordinate the abuse of a four-year-old necessitates permanent and stringent monitoring of her conduct and digital access. Any further sexual misconduct or breach of her life-long notification requirements in Ashton-under-Lyne, Manchester, or elsewhere will result in immediate arrest and a return to the court system for further incarceration.
