Dozens of Ethiopian Christians were arrested for holding a prayer meeting, though under charges of "mixing with the opposite sex": "the Saudi officials are accusing the Christians of committing the crime of mixing of sexes because if they charge them with meeting for practicing Christianity, they will come under pressure from the international human rights organizations as well as Western countries."
The women among the Christians were strip-searched and the men assaulted (http://www.christianpost.com/news/ethiopian-christian-prisoners-assaulted-strip-searched-in-saudi-arabia-68013/). It is instructive that this was a purely prayer meeting among Christian foreigners and did not involve any proselytization of any moslem or Arab.
As at early February 9 the Christians were still being held without trial. (http://www.charismanews.com/world/32553-saudi-arabia-arrests-ethiopian-christians-for-mixing-with-the-opposite-sex)
