Torrens Knight (born 4 August 1969) is a Northern Ireland loyalist, who belonged to the North Antrim and Londonderry Brigade of the Ulster Defence Association (UDA). In 1993 he took part in the Greysteel massacre (in which eight civilians were shot dead) and the Castlerock killings (in which three civilians and a Provisional Irish Republican Army (IRA) member were killed). After being convicted—along with three others—for the killings, he served seven years in the Maze Prison before his release in 2000 under the terms of the Belfast Agreement.
Knight spent his formative years living at his grandmother's farmhouse in the rural area of Aghadowey after the split of his parent's marriage. In adulthood he developed an addiction to poker gambling machines which resulted in his exposure of stealing money from his grandmother to fund his habit. As a result of this he was asked to leave the home and subsequently moved to the mostly Protestant town of Portstewart. Living with a loyalist, he started drinking alcohol and involving himself with criminality.
His initial starting point within loyalism was selling a magazine for a loyalist prisoners association. He progressed to the ranks of the UDA and carried out acts like robberies and punishment beatings. Knight was part of a four-man UDA group sent to conduct an attack in revenge for the Shankill Road bombing. Their target was the Rising Sun bar in Greysteel, where Knight, Stephen Irwin, Jeffrey Deeney and Brian McNeill shot eight dead (six Catholics and two Protestants). After the leading gunman, Irwin shouted "Trick or treat", he and Deeney raked the bar with gunfire, while Knight, armed with a shotgun, stood at the door. 19 other people were injured. McNeill was the driver of one of the cars used after the shootings. The attack was claimed by the "Ulster Freedom Fighters", a covername used by the UDA.
Knight was given eight life sentences for his part in the killings and a further four more for the killing of an IRA member and three Catholic civilians in Castlerock, County Londonderry. He served seven years in the Maze Prison before paramilitary prisoners were granted a general release under the Good Friday Agreement in 2000.
