Apparently, two sisters went to the woman to help cure their sick father who could not be helped by doctors. They paid the suspect some 5300 shekels (about $1400) but his condition did not improve.
The police department did not say that they were arresting the woman for fraud. They said that they arrested her for suspicion of engaging in witchcraft.
This is a regular occurrence in Saudi Arabia, but it is relatively rare to hear about this in the PA. It sounds, however, as if they have a similar law on the books outlawing sorcery.
