A Dhaka court yesterday denied bail to wife of former Bangladeshi President H.M. Ershad and allowed police to hold her for up to 72 hours while they quiz her about allegations of misappropriating funds. Bidisha, who was arrested overnight at her apartment in the capital Dhaka, asked the court to free her, arguing she was the victim of a political conspiracy. Bidisha was detained after her husband filed a complaint, accusing her of misappropriation of money and issuing threats. Official sources said Bidisha was likely to be questioned on her alleged links with foreign intelligence organizations.
