The teenager who murdered schoolboy Rhys Jones has been attacked in jail, the Prison Service has confirmed.
Sean Mercer, 18, was assaulted at HMP Moorland in Doncaster, South Yorkshire, but the incident was stopped by the "timely intervention" of staff.
The teenager was taken to hospital after the attack on 27 December, where he is thought to have been treated for a broken nose and facial injuries.
Mercer, of Croxteth, Liverpool, was jailed for 22 years last month.
