The gang's name derived from a farm in Glenanne, County Armagh, which was owned by RUC reservist, James Mitchell. Weir maintained that it was used as a UVF arms dump and bomb-making site. The bombs which were used in the UVF's 1974 Dublin and Monaghan bombings were built and stored on the farm. Weir claimed Mitchell had admitted to him that he had been involved in the bombings and he had personally seen Mitchell mixing home-made ammonium-nitrate-and-fuel-oil explosive in the farmyard on one occasion.
