A porter at Great Ormond Street Hospital has been charged with 84 sexual offences against children.
Paul Farrell, 55, is accused of committing offences against seven victims between 1985 and 2018.
The children’s hospital said it was working closely with the police, and that an individual had been dismissed.
A spokesman said the charges were “truly awful”, safeguarding children was “fundamental [and] our policies are in line with national best practice”.
“If patients, their families or colleagues raise concerns about staff there is a clear and swift process to manage these concerns when they are raised. This includes involving the police where needed.”
The defendant, of Castle Road, Camden, is due to appear at Wood Green Crown Court on Friday, charged with offences including rape and sexual assault.
According to the Sun newspaper, Farrell worked at Great Ormond Street Hospital for Children in central London from the mid-1980s until his arrest in January.
An ongoing investigation is being led by officers from the Metropolitan Police’s Central North Command Unit safeguarding team.
