DAMMAM: The investigation into Manal Al-Sharief, the woman held in a Dammam prison after being arrested last Saturday for driving in Al-Khobar, has widened to include two other women for their role in the incident, Al-Watan Arabic daily reported Friday. The newspaper quoted sources as saying that an order to summon for questioning had been issued for one woman believed to have filmed Al-Sharief as she drove her car, and another said to be the supervisor of the “I'll Drive My Car Myself” Facebook campaign on the Internet, described as a university student and friend of Al-Sharief. When contacted by Al-Watan, the first woman denied any connection to the campaign, saying only that she was a “sympathizer; and “supporting member”. According to the newspaper, the summons for questioning was made after Al-Khobar Police presented a list of names to the Eastern Province Emir's Office which ordered the immediate detention of the women whose names are on the list and that their statements be taken on the aims of the campaign. Manal Al-Sharief, meanwhile, had her detention at Dammam's Women's extended for 10 days from Thursday. Saudi Gazette reported Friday that her lawyer, Waleed Abu Al-Khair, told The Associated Press that the prosecutor general had extended her detention by “another ten days while she is investigated”, a move he described as “a message that any woman who dares to drive her car will face the same fate”.
