In 2026, the Offender Database recorded that 22-year-old Christopher Hartley—of HMP Doncaster (formerly of Adwick-Le-Street)—was jailed for 17 years for the “terrifying” rape and strangulation of two teenagers he met via the dating app Tinder. Hartley appeared at Sheffield Crown Court where he was found guilty of seven offences, including rape, sexual assault, and attempted strangulation to commit rape. It was reported that the investigation established Hartley targeted his victims—aged 16 and 18—in separate incidents between 2018 and 2019, using “extreme violence” to gain power and control.
The investigation established that Hartley lured his first victim, a 16-year-old girl, to a remote area near Adwick-Le-Street under the guise of a dog walk. The prosecution reported that when she refused his sexual advances, he placed her in a headlock and squeezed her neck until she feared for her life before raping her. In the second attack, the investigation established Hartley drove an 18-year-old victim to an isolated location in Derbyshire, where he strangled and raped her inside his vehicle.
Judicial Findings and Investigative Detail
The court reported that both survivors suffered profound psychological trauma and genuine fear of death during the attacks. The investigation established a “predatory pattern” in which Hartley utilized Tinder to identify young women before moving them to secluded spots where they could not escape or call for help. The prosecution reported that Hartley’s use of strangulation as a method of control was a particularly aggravating factor, identifying him as a significant danger to the public.
Judge-led proceedings at Sheffield Crown Court concluded with Hartley being sentenced to 17 years in prison, with an additional four-year extended licence period. For his actions in Doncaster and Derbyshire and the “violence and control” reported, he was designated as a dangerous offender. The judge noted that the severity of the serial attacks necessitated lifelong restraining orders to protect both survivors and a lifetime notification requirement on the sex offenders register.

Monitoring and Public Protection
Hartley is managed as a Very High Risk dangerous sex offender within the prison system and will be subject to the most intensive tier of statutory supervision for the remainder of his life. Due to the nature of his conduct—specifically his “calculated use of Tinder to lure victims to isolated death-trap locations”—his management is a priority for the Multi-Agency Public Protection Arrangements (MAPPA) at Level 3. Authorities state that his propensity for using physical violence to enforce “power and control” identifies him as an individual who requires permanent exclusion from all digital dating environments and intensive forensic monitoring upon any potential release.
As a registered sex offender for life, the 28-year-old’s details are permanently logged on the national police database. Authorities state that the lifelong restraining orders are vital safeguards to ensure the survivors are protected from further contact. Any change of residence in Doncaster or elsewhere, any attempt to access restricted apps, or any unauthorised presence in isolated rural areas will result in immediate arrest to ensure the ongoing safety of the public from a man who demonstrated a “violent and predatory intent” to violate young women.
QUESTION – Given that the offender specifically used “Dog Walking” and “Car Rides” as ruses to lure victims to isolated spots, do you believe that “Geographical Exclusion Zones” for remote woodland and parks should be a mandatory lifetime license condition for all violent rapists?
