I have a friend (female) who was charged with molesting a child she was babysitting. At the time she was 16, and the child was 4. The two families had been friends for many years and lived on the same street, and she had babysat the child dozens of times.
One day the child's parents noticed something like diaper rash, and they immediately jumped to the conclusion that my friend had molested their child. They called the police and had her charged. The police went to her school to make the arrest, and although they didn't burst into her classroom, they led her away into a police car while everyone could see from the windows. It cost her parents thousands in legal fees only to see it tossed out of court when the kid's parents were unable to find a single medical professional who would state that the rash could have been caused by any type of molesting.
The reason the kid's parents kept pushing the case was that when they asked the child if my friend had touched her in a private place, the child said yes. My friend agreed - when the kid soiled his pants, she changed his pants and cleaned him up. The parents kept pressing the child for details and eventually the kid started to cry. That somehow convinced the parents that the child had been molested!
There was no evidence, the child never claimed there was anything going on, and kept asking when (my friend) was going to come over and play again.
It nearly ruined her life because with that on her record she could not be credentialed as a teacher, which was her goal. They managed to get it expunged finally.
