CROSSBOW Cannibal serial killer Stephen Griffiths dodged death when another con tried to plunge a wooden spear into his heart.
Horrified prison officers rushed to save the monster, 49, as he lay screaming in pain.
They restrained the other lag while Griffiths, who murdered three prostitutes before eating their body parts, was rushed to hospital.
He had a “large puncture wound” to his chest and was last night back at top-security Long Lartin jail, Worcs, on the hospital wing.
A source said: “The other inmate used a sharpened piece of wood and drove it in as hard as he could.”
The triple-killer got a whole life term in 2010 for the Bradford murders of Susan Rushworth, 43, Shelley Armitage, 31, and Suzanne Blamires, 36 — seen on CCTV being shot in the head with a crossbow.
Sources say the con who attacked him has since been placed in segregation.
A Prison Service spokesman said: “A prisoner at Long Lartin received hospital treatment after an incident on Friday. The prisoner returned to the prison later the same day and the matter has been referred to the police.”
