Terry Regan, 44, from Bolton upon Dearne, South Yorkshire, said he had come face-to-face with the intruder and had been "terrified and I grabbed hold of a knife and stabbed him in the ankle area". He added: "I realise what I have done and I would do the same again."
Mr Regan met the intruder in his kitchen while investigating a noise. The men are believed to have struggled for several minutes before the intruder suffered five stab wounds to the leg.
Chief Inspector Robin Caulfield, of South Yorkshire Police, said the intruder, who scrambled through a window to escape, called for an ambulance himself. A 23-year-old man was later arrested and was treated in hospital for leg injuries.
Mr Regan was questioned for 12 hours before being released on police bail. He could face wounding and assault charges.Reuse content
