".... 2. During the course of the fight with Simon Scott, I picked up a knife which Rosa had left on the three-wheeler pushchair. I had not armed myself with a knife before Scott knocked on the door. 3. The knife .... which was seized from my right-hand jeans pocket I obtained from the kitchen and put in my jeans after Scott had left my flat and before the police arrived. I had armed myself at that stage in case Scott returned. It was never used. .... 7. Simon Scott had caused various problems for us prior to the incident because of his lifestyle. He had noisy parties at all times of the day and night and he was always drunk and/or under the influence of drugs. He also dealt drugs from this flat and there were numerous visitors to his flat. 8. The reason Scott came to my flat was because Rosa had stolen a lump of crack cocaine from him. 9. When Scott first started attacking us I feared for the safety of Rosa and our baby. I have myself been seriously assaulted in the past. Two people broke into my previous house and attacked me with a knife when I was in bed with my baby by a previous partner. 10. I picked up the knife from the pushchair and during the course of the fight stabbed Scott in the throat and also caused the other injuries described by the doctor. I accept that this was an extreme use of force in the circumstances."
