In 2018, the Offender Database recorded that 36-year-old Matthew Fox and 33-year-old Katherine Slym were each jailed for 20 months for the sexual exploitation of a 14-year-old girl. Fox and Slym—both of Tedder Road, York—groomed the youngster before inviting her to a “sexual encounter” in a Huddersfield hotel room in 2016. It was reported that the couple, who were drunk at the time, engaged in sexual activity with the girl and performed sexual acts in front of her.
The investigation established that the defendants had a “lengthy conversation” with the victim earlier that day, during which they discussed tattoos and the girl explicitly stated she was only 14. West Yorkshire Police reported that the pair took selfies with the child before leading her to the hotel. The prosecution reported that once inside the room, the girl was also encouraged to drink alcohol and smoke cigarettes with the adults.
Judicial Findings and Investigative Detail
The court reported that the girl felt “used” during the prolonged incident, which only came to light after she confided in a friend. Leeds Crown Court heard from Fox’s barrister that the couple were “liberally minded” but had “crossed the line” by ignoring the girl’s age. The investigation established that there was a marked disparity in age and that both defendants had ample time to “come to their senses” and halt the abuse.
Judge Robin Mairs presided over the sentencing, stating that the element of grooming made an immediate custodial sentence the only justified outcome. For their actions in Huddersfield and York, Fox and Slym were sentenced to 20 months in immediate custody. The judge also ordered both individuals to sign the Sex Offenders Register for ten years, noting that Slym had already lost her employment as a direct result of her predatory behaviour.

Monitoring and Public Protection
Fox and Slym are managed as registered sex offenders within the York area. Due to the nature of their conduct, which involved the coordinated grooming and sexual exploitation of a stranger in a hotel environment, their management remains a focus for the local public protection units. Authorities state that their “liberally minded” justification for abusing a 14-year-old indicates a lack of fundamental boundary recognition regarding child protection.
As registered sex offenders until 2028, their details are permanently logged on the national police database. Authorities state that their notification requirements include providing details of any temporary residency, such as hotel stays. Any failure to notify police of their location, any attempts to approach minors in Huddersfield or York, or any further “grooming” style interactions will result in immediate arrest to ensure the ongoing safety of the public from their demonstrated pattern of joint sexual offending.
QUESTION – Given that the couple used “drunkenness” and a “liberally minded” lifestyle as a partial explanation for their crimes, do you believe that any adult who engages in “group sexual activity” involving a minor should face a mandatory minimum sentence of 5 years, regardless of their level of intoxication?
