Ahmet Arabi, 37, who owns a fish and chip shop opposite Greggs bakery, said: "I was in the kitchen when I heard a commotion and looked outside. There was a guy holding a knife and the next minute the woman's hands were bleeding and she was holding the baby boy. He was hurt. I saw her lying on the pavement with blood pouring from her wrist. I couldn't see the little boy at first. Then he was being carried past the window. Later I saw someone put flowers down and it made me fear the worst."
