BBC: A Saudi law professor who wrote about a possible power struggle over the royal succession is being held without charge, a human rights group says.
Mohammad al-Abdulkareem, 40, was detained at his home in Riyadh on Sunday by four men who had no court warrant, the group said.
Mr Abdulkareem's article appeared shortly after King Abdullah, 86, went to America for surgery on his spine.
The royal succession is a highly sensitive subject in Saudi Arabia.
There has been no official confirmation of the arrest by the Saudi authorities. >>> Sebastian Usher. BBC News, London | Tuesday, December 07, 2010
