The police source said Bilal Abdulla, another doctor called Mohammed Asha and his wife were among those arrested. According to Britain's General Medical Council, Abdulla qualified as a doctor in Baghdad in 2004 and is a registered medical practitioner in Britain. A switchboard operator at the Royal Alexandra Hospital in Paisley, near Scotland's biggest city Glasgow, said Abdulla worked there. Asha qualified as a doctor in 2004 in Jordan and is also a registered medical practitioner in Britain. British media said Asha worked at a hospital in central England.
