THE teenager who shot Liverpool schoolboy Rhys Jones stabbed the killer of former altar boy Jimmy Mizen during a prison brawl in South Yorkshire, sources have confirmed.
Sean Mercer, 18, attacked Jake Fahri, 19, with a pair of tweezers which had been sharpened and bound with tape to create a makeshift knife, it was alleged.
The incident, which happened in the exercise yard at Moorlands Young Offenders’ Institute in Doncaster on Monday also involved a third youth who held Fahri down during the attack.
Fahri, serving 14 years for slashing the throat of 16-year-old Jimmy following an argument in a London baker’s shop in May last year, was later taken to hospital and treated for stab wounds.
Mercer, serving 22 years for shooting Rhys, 11, dead during a gang war in Liverpool, has been moved to an isolation wing.
A Prison Service spokesman said: "On Monday a fight broke out between three prisoners at HMP and YOI Moorland.
"Staff acted quickly to control the situation and one prisoner was taken to an outside hospital for treatment.
"Police have been notified of this incident and are investigating."
A spokeswoman for South Yorkshire Police said inquiries were continuing.
