Right after you regain control over the Batman, use the hook to get onto one of the statues under the ceiling. Just like in the case of the previous situations of this kind, it pays off to move around the hall by using these vantage points. They can also be useful while performing the inverted takedowns and attaching the enemies using the claw.
An important new element of this event is that, in the bank, you will meet an enemy using a disrupting device for the first time so, you will not be able to use the detective vision at first, to follow the actions of the other enemies. I recommend, therefore, that you locate this character as quickly as possible (you will recognize hi by the antenna sticking out of the device on the enemy's back) and neutralize him.
When it comes to the elimination of the remaining enemies, you can use the proven methods of attack from above and hiding in the venting shafts for quiet takedowns, among others. While clearing the bank's main hall, you can find the explosive gel useful because, both o the ground floor and in the side rooms, located on this upper floor, there are many walls that can be destroyed.
Continue neutralizing the bandits , until the moment in which there will be only one man standing in the room. This character should give up automatically, so, you need to approach him and press the key/button that the game prompts you to, in order to start interrogation and learn about the possible whereabouts of the Joker.
