The Doctors and Nurses treating baby Charlie Gard at Great Ormond Street Hospital have received death threats alongside thousands of abusive messages.
The hospital have confirmed that the police had been called to investigate the threats and “unacceptable” harassment of it's staff.
Staff have received abuse in the street as well as via online messages.
The hospital also said that other parents and family members visiting sick children in the hospital have also been affected by the intimidation.
Mary MacLeod, chairman of Great Ormond Street Hospital, said; “Charlie Gard's case is a heart-breaking one. We fully understand that there is intense public interest, and that emotions run high".
“We recognise the tireless advocacy of Charlie's loving parents and the natural sympathy people feel with his situation."
"However, in recent weeks the GOSH community has been subjected to a shocking and disgraceful tide of hostility and disturbance. “Staff have received abuse both in the street and online. Thousands of abusive messages have been sent to doctors and nurses whose life's work is to care for sick children. Many of these messages are menacing, including death threats.”
The Metropolitan Police have said;: “We will do everything possible to hold to account anybody who involved in this kind of deplorable behaviour.”
Charlie's parents said in a statement: "We don't condone abusive or threatening behaviour to GOSH staff or anybody in connection with our son.
