Story summary

Martin Gallacher, a computing teacher in Paisley, Renfrewshire, was recently convicted of grooming and sexually assaulting 12 students over an 11-year period from 2013 to 2024. Despite being described as "the perfect teacher" who had won awards for his teaching excellence, Gallacher was found guilty of abusing his position to manipulate and prey on teenage boys. He carried out the abuse in various settings including classrooms, lunch clubs, badminton and football teams he coached, and even through online platforms such as PlayStation, Discord, Steam, and Snapchat. Prosecutors argued that a sexual harm prevention order should be imposed to limit Gallacher's future contact with potential victims, while non-harassment orders would prevent him from contacting his known victims.
