Aidan Kehoe, chief executive of the Royal Liverpool & Broadgreen University Hospitals, said:
"I – along with staff at our hospitals – have been upset and disheartened by the ongoing abuse and threats aimed at our colleagues at Alder Hey and other NHS staff in the past few weeks."
"We recognise that this is a very emotional and sad case and respect that everyone is entitled to their personal opinions. But no one has the right to threaten or abuse. We fully endorse the messages sent by Alder Hey about this and hope that those responsible for this abuse will think very carefully about the impact they are having on front-line hospital staff."
