Staff at the hospital treating terminally-ill boy Charlie Gard have received death threats, it has emerged. Great Ormond Street Hospital says it has contacted police following a tide of “shocking and disgraceful” hostility and disturbance both in the street and at the London medical facility.

Thousands of abusive messages have been sent to doctors and nurses, and families visiting their children at the hospital have been “harassed and discomforted”. Charlie’s parents have been battling in the courts for permission to take him to America for treatment but Great Ormond Street says this would not help.

A judge at the High Court has been hearing evidence about the potential of an experimental treatment that it is claimed could help the baby. The court has previously ruled in favour of the hospital and said 11-month-old Charlie should be allowed to die with dignity. The court is due to hold a hearing to consider the latest developments on Monday.
