In a massive development in the INX Media case, Karti Chidambaram, son of former Union Finance Minister P Chidambaram was arrested by the Central Bureau of Investigation (CBI) from the Chennai airport on his return from London this morning.

The arrest comes in the wake of Karti’s chartered accountant S Bhaskararaman being arrested recently from a five-star hotel in New Delhi on February 16.

According to sources, Karti Chidambaram was detained by the Immigration officials immediately after his arrival and taken into custody by CBI officials. It is also learnt that he is likely to be flown from the airport to New Delhi.

The CBI has accused Karti of receiving money from INX Media for using his influence to manipulate a tax probe against it in a case of violation of Foreign Investment Promotion Board conditions in 2007 to receive investment from Mauritius.
