On asking, the TI told Ahemed that he will be prosecuted under the MV Act for talking over mobile phone while driving. Ahmed denied the charge and refused to submit his driving licence. However, when Mondal told him that his vehicle will be handed over to the local police station unless he provides his driving licence, Ahmed complied. Soon after, he called someone and told Mondal that ADG Law and Order will talk with him. When Mondal took his phone, a person from the other end told him to release the vehicle without any prosecution. He identified himself as ADG Law and Order Anuj Sharma. After hanging up, Mondal sensed some foulplay. He immediately started verifying the phone number. Seeing this, Ahmed started threatening the TI. He called up the number again and handed his mobile phone to Mondal. The person on the other end also threatened him of dire consequences.
