Pramanik, who has been re-nominated by his party this time from Cooch Behar, argued with the team that stopped him in Dinhat area, saying that since the vehicle belonged to a Union minister, it could not happen. The investigation was conducted in this manner.

However, the team of police and Election Commission officials refused to accept his argument and eventually checked the entire vehicle including the bags inside it. However nothing was recovered.

Trinamool Congress general secretary Abhishek Banerjee objected to his helicopter being searched by a team of Income Tax officials on Sunday. Banerjee later clarified that her objection was not related to the searches, but to the Income Tax authorities' refusal to allow testing of the helicopter even after the search operation was over.
