Two people were last night found stabbed to death in Antrim in what police believe was a violent domestic incident. The RUC was called to a house in Firmount Drive, on the Ballycreaigy Estate in the town, at about 7 p.m. They found the woman in the back porch and the man in the living room. Both had stab wounds. The couple, who were in their twenties, were given first-aid until an ambulance arrived, but they died at the scene.
