Several hospital staff have been suspended and an investigation is under way after an incident involving the care of a patient in Kent.
Both East Kent Hospitals NHS and Kent Police are investigating the alleged assault on 15 December at the William Harvey Hospital in Ashford.
The trust also runs the QEQM hospital in Margate which has been criticised over a seven-day-old baby’s death.
