Karti Chidambaram is son of former Union minister P Chidambaram.

The CBI today asserted in the Supreme Court that there was "good, cogent" reason for the lookout circulars against former Union minister P Chidambaram's son Karti Chidambaram in connection with a case of alleged corruption.A bench headed by Chief Justice Dipak Misra took on record the documents placed by CBI in a sealed cover in connection with the case.The bench, also comprising Justices A M Khanwilkar and DY Chandrachud, asked the CBI to respond to the affidavit filed by Mr Chidambaram in connection with his questioning by investigators before whom he had appeared on August 23 and 28.Additional Solicitor General Tushar Mehta told the bench that there was "a good, cogent reason for issuance of lookout circular against him (Karti). It is not a simple case or that of one company but it involves jugglery of accounts and properties abroad".Appearing for Mr Chidambaram, senior advocate Gopal Subramanium submitted on his behalf, "What is the subject matter of enquiry is not me but my father who happened to be the finance minister giving Foreign Investment Promotion Board (FIPB) approvals to a company in 2007 and it is alleged that one of the conditions had been violated".

He added that not a single person of the six-member FIPB, who were secretary-level officers, had been examined in the case.The Supreme court has posted the matter for hearing on September 11.
