Medical staff at the hospital treating sick baby Charlie Gard have received death threats, it has emerged.
But the case was reopened earlier this month at England's High Court after two overseas hospitals approached GOSH with possible evidence of alternative treatments that might help Charlie's condition.
Reacting to the abuse directed at staff Mary MacLeod, chairman of the hospital, said in a statement: "Great Ormond Street Hospital cares for many thousands of seriously unwell children every year, providing outstanding treatment for those who need it most".
Charlie has a rare genetic condition that causes progressive muscle weakness and brain damage.
After the hospital's lawyer, Katie Gollop, told a judge what doctors thought of results from new scans of Charlie's brain, the baby's mother, Connie Yates, burst into tears, and his father, Chris Gard, yelled "evil", according to the association.
"The GOSH community has been subjected to a shocking and disgraceful tide of hostility and disturbance".
The hospital have confirmed that the police had been called to investigate the threats and "unacceptable" harassment of it's staff.
The hospital is in close contact with the Metropolitan Police over the incidents, she added in a statement. Hirano devised the experimental treatment that Charlie's parents want the infant to undergo. As The Guardian reports, the Great Ormond Street Hospital has now received thousands of abusive messages from those opposed to removing Charlie Gard from life support.
Supporters outside after they hear the news
MacLeod said Charlie's case was a "heart-breaking one".
Charlie Gard's parents have said they are "extremely upset" by the backlash they received after GOSH revealed the abuse its staff was suffering.
The Gards, whose case is being followed by US President Donald Trump, were last week granted legal and permanent residence by the US Congress in order to pursue the experimental treatment.
But the couple say there is new evidence and had asked Mr Justice Francis, who in April ruled in favour of Great Ormond Street and said Charlie should be allowed to die with dignity, to change his mind.
The hearing was held in advance of the trial, scheduled for Tuesday at the UK High Court.
Dr. Michio Hirano, the medical director of the Laboratory of Metabolic and Mitochondrial Disease in NY who flew to the United Kingdom to assess Charlie, argued last week that his experimental drugs still had a chance of helping the boy.
A lawyer representing the hospital said in a brief hearing Friday that the latest brain scan results make for "sad reading".
