A robber who chopped off half of his ear was on the run last night after the ambulance taking him to hospital was ambushed by masked men carrying baseball bats. Michael O'Donnell, 28, was found in his cell in early on Sunday with the top part of his left ear missing. Three prison officers accompanied him in an ambulance but four men jumped out of a stolen car, halted the ambulance and freed him.

Hmmm ... baddies with hard-core self-discipline ...
