The Central Bureau of Investigation (CBI) in an affidavit before Bombay high court sought dismissal of IRS officer Sameer Wankhede’s quashing petition in an alleged corruption case against him, and to recall the interim protection granted by the vacation bench last month, against his arrest as it would adversely interfere with the ongoing investigations. The CBI said it has a 'prima facie case' against Wankhede, former zonal director of Narcotics Control Bureau (NCB).
