The CBI on Tuesday pleaded for withdrawal of proceedings against Italian businessman Ottavio Quattrocchi in the over two-decade-old Bofors pay off case. The investigating agency said it has got no fresh instructions from the government in the wake of the Income Tax Appellate Tribunal (ITAT) order. The Chief Metropolitan Magistrate, who had earlier heard the arguments of all the parties including the CBI, heard the agency's contentions after the recent ITAT order. The ITAT order, which had on Monday said that kickbacks were paid to the late Win Chaddha and Quattrocchi in the Howitzer gun deal, was placed before the court. The Tribunal had said that they were liable to pay income tax.
