New Delhi, February 16: The Income Tax department's 'survey' at the BBC office here continued for the third straight day on Thursday as officials gathered financial data from select staffers and made copies of electronic and paper data of the news organisation.

The operation that began at the British Broadcasting Corporation (BBC) offices in Delhi and Mumbai around 11:30 am on Tuesday has clocked more than 45 hours now, officials said. Income Tax Surveys at BBC Offices: IT Survey at British Broadcasting Corporation in Mumbai and Delhi 'assault on Press freedom', says NTK Chief Seeman.

The survey is going on, they told PTI. Authorities had said on Wednesday that the exercise would continue for some more time, saying the "exact time frame to call the operation closed rests entirely on the teams on the ground".

IT Officials Continue 'Surveys' at BBC Offices:

The survey is being carried out to investigate issues related to international taxation and transfer pricing of BBC subsidiary companies, officials have said. The survey teams are seeking answers on financial transactions, the company structure and other details about the news company, and are copying data from electronic gadgets as part of their task of collecting the evidence, tax officials had said.

Opposition parties have denounced the I-T department action against the London-headquartered public broadcaster, terming it "political vendetta". On Tuesday, the ruling BJP had accused the BBC of "venomous reporting" while the Opposition had questioned the timing of the action that came weeks after the broadcaster aired a two-part documentary "India: The Modi Question" on Prime Minister Narendra Modi and the 2002 Gujarat riots. Income Tax Surveys at BBC Offices: Aware of the IT Raid; Cannot Offer Any Judgement, Says US.

While there has been no official statement from the Income Tax department on the action, the BBC has said it was cooperating with the authorities. A BBC staffer in Delhi said they were broadcasting their news like usual.

The Supreme Court last week dismissed a plea seeking the imposition of a complete ban on the BBC in India in the wake of the controversial documentary, terming the petition "entirely misconceived" and "absolutely meritless".

Another set of petitions challenging the government's decision to block the documentary's access on social media platforms will be heard in April. On January 21, the government had issued directions to block multiple YouTube videos and Twitter posts sharing links to the documentary. '
