Appeal for victims of travelling salesman sex offender to come forward
Police believe there could be victims all over the country of a travelling salesman jailed for multiple sexual offences against girls, including some in Northamptonshire.
Luke Williamson, 34, was jailed at Hull Crown Court for eight years, with another three years on licence, in January. He admitted carrying out 20 sexual offences across East Yorkshire, West Midlands, Hertfordshire and Northamptonshire.
Now detectives have appeared on BBC Crimewatch to appeal for other victims of Williamson, of Kempston, Bedford, to come forward.
Williamson sent thousands of messages, including videos and voice calls, through multiple social media channels to three teenage girls all under 16 years old, living in Northamptonshire, the West Midlands and Hertfordshire, leading them to believe he was in love with them and manipulating them into doing what he wanted for his own perverse sexual gain.
Williamson was charged in July 2025 and pleaded guilty in October 2025 to 12 counts of arranging or facilitating the commission of a child sexual offence, three counts of sexual communications with a child, three counts of making indecent photographs of a child, causing a child to watch a sexual act and taking indecent photographs of a child.
The investigation commenced when Williamson’s phone was seized in May this year as part of another investigation and examined by our Digital Forensics Unit who uncovered the messages, images and videos he had been sending.
It was established during the investigation that Williamson drove significant distances across the country to meet the girls, and location tracking data analysed from his phone showed that he would wait for hours in his car to execute his plan.
On one occasion, he went to such lengths that he meticulously planned and implemented entering one of the girl’s houses whilst her family members slept to engage in sexual activity with her.
Speaking on BBC Crimewatch this week, Det Insp Cat Slaughter and Det Con Stacey Waslin from Humberside Police appealed for other victims of Williamson to come forward.
Det Inps Slaughter said: “He would manipulate [his victims] into thinking they were in a relationship with him and because of this, many don’t see themselves as victims.
“It’s not just teenagers we are appealing to; some victims may even now be older, or someone they know may have been in contact with him, and they recognise his photo, to come forward.”
Det Insp Waslin stressed that victims may feel shame and embarrassment but added that it is “absolutely not the victims’ fault”.
She said: “If you have been in contact with him, it is important you get the support you need.”
