Bahrain Student Protesters In Prison
11 October 2011
In the absolute monarchy Bahrain, people may be arrested for many reasons or pretexts. You may be arrested for supporting human rights; for playing as a child; for treating wounded patients if you are a doctor; for photographing if you are a photographer; for a sense of humour if you are a blogger; etc. etc.

Man arrested for cross-dressing in Bahrain
Suspect says work at beauty salon demands fashionable, elegant looks
By Habib Toumi, Bureau Chief
12:09 July 7, 2014
The expatriate Arab was arrested by a police patrol as he was walking “in a feminine way” in the Bahraini capital Manama and attracted the attention of the servicemen.
He said that he worked in a women’s beauty salon and that his profession demanded that he always looked elegant and wore the latest fashion accessories to set a positive example for his clients.
The public prosecution was not convinced by the arguments and charged him with encouraging debauchery. He was subsequently referred to a court that ruled to keep him in jail for one month.
Foreigners who are apprehended for their “unacceptable looks” in public are often jailed for a short period before they are sent home.
