Even before the Mumbai blasts have really made any significant headway a man detained over blasts probe has died during the questioning. The ATS was questioning Faiz Usmani, over what he may have known about the serial blasts that shook Mumbai on Wednesday evening. He was detained on Saturday for questioning when he 'fell ill' during the interrogation. Faiz Usmani's family alleges that excesses on part of the police caused his death.
