In a first, Mumbai police used a drone that played an audio message asking people not to gather at the ED office. The audio played on the drone asked people to maintain law & order and voice their opinions in a peaceful manner. NCP supremo Sharad Pawar had earlier announced that he would visit the ED office today. Remember, Pawar had been booked by the ED in connection with the MSC bank scam. Pawar dropped his plan at the behest of the police & ED.
