NEW DELHI — India’s premier investigative agency again sought withdrawal of the case against Italian businessman Ottavio Quattrocchi in the Bofors payoffs scam citing lack of evidence, even after a tax tribunal sensationally ruled that illegal commissions were indeed paid in the Rs15-billion gun deal of 1986. A Delhi lower court hearing the matter deferred the decision for Thursday after the Central Bureau of Investigation (CBI) and advocate Ajay Agarwal, who is challenging the CBI plea, made their observations.
