NEW DELHI (TIP): The CBI grilled Karti Chidambaram for about eight hours in connection with an alleged irregularity in Foreign Investment Promotion Board (FIPB) clearance given to a media group, INX Media, for receiving funds from Mauritius when his father P Chidambaram was the Union Finance Minister.

The CBI investigators prepared 100 questions on different aspects of the case to ask Karti, who was directed by the Supreme Court to appear for questioning, sources said.

Karti reached the CBI office at about 10.20 am and left around 7 pm. He would again be examined on August 28 along with four other accused. Karti is the first person in the case to be questioned in Delhi.

It is alleged that a firm “indirectly controlled” by him received money from INX Media, run by Indrani and Peter Mukerjea who are in jail in the murder case of Indrani’s daughter Sheena Bora. The CBI had issued a notice to Karti to appear for questioning in June but he had sought time.

Later, a lookout circular was issued against him to prevent him from leaving the country. Karti then approached the Madras High Court, which stayed the circular.
