I have no idea if and when that may have happened (or not happened) but that is condemnable
if it did.
As I have been repeatedly saying in this thread or elsewhere, Saudi law is Orthodox law the same as
observed by the Taliban's. It's a pity that super powers  go bombing the Talibs but ignore Saudia  
  obviously  for good reasons no more a secret!!
According to the best of my knowledge an aged woman is 
not required to  veil or wear burqa.  She is also  not stopped from going out alone if  
she  needed to accomplish her errands.  I don't understand what could be the circumstances 
in her case that  led to  punishment by the Saudis..? perhaps the matter relates more to custom and 
culture rather than religion...I have known such thing happen anywhere...
As Kimmy stated in one of her posts Islam focuses on FAMILY rather than SEX...
and Muslim men and women are barred from premarital sex. Segregation of sexes is not
totally banned but proper veiling is bidden for women who work in offices or who have to move around.
 Condition of escort (not by a stranger) for young women is not a religious command but  is subject 
 to  socio-cultural structure or custom...for example, a woman needs an escort in Afghanistan, Pakistan,
or Somalia but not in Japan, Uk, or South Africa, etc just for those reasons.
Breast feeding: If a woman breast suckles a baby or a small  suckling he spontaneously
becomes her son...or daughter and they cannot inter-marry with any of her children.
 
As I said Sharia is a two-way system...If any Muslim state cannot give Rights it can
Neither ask them Duties!! Simple as enough but if someone, say Saudi, does that
you have no reason to malign Islam. Islam is by the Quran as Christianity is by the
Bible!! Rest is secondary and controversial.
