A patient says she was raped between 50 and 60 times while at an NHS psychiatric hospital in Dartford, Kent, by one of the people who was supposed to be looking after her.
The woman, who is now in her 40s and a mother of two, says the care worker told her he would help get her discharged if she did as he demanded.
