NEW DELHI: The income tax department is “aggressively” pursuing names that emerged in the Panama Papers , including Bollywood superstar Amitabh Bachchan , and has dispatched a top-level officer to the British Virgin Islands to access information, a senior official has said.

The British Virgin Islands in the Caribbean is considered to be among several tax havens. The tax department has launched 33 prosecutions linked to the names revealed in the Panama Papers and is probing others.

“There is no let-up in investigations. We are aggressively seeking information from other countries,” the official, who did not wish to be identified. After Pakistan PM Nawaz Sharif was removed by the country’s top court in connection with the Panama Papers case, there has been criticism that tax authorities in India are dragging their feet.

Asked whether information linked to the allegations against Bachchan was being pursued, the official said: “Mr Bachchan has said he does not own any of the firms named in the documents. So we just can’t launch a probe. We have to seek information.”

“We have sent a senior CBDT (Central Board of Direct Taxes) officer to the British Virgin Islands to gather information and we are also seeking information from various other countries and then we will have to analyse and see if there are any violations,” the official said.
