When you arrive at the Bank, you'll be welcomed with another short scene. Looks like we'll need to round up the robbers, which is pretty straightforward.
To catch the first clown, just keep following him and crashing into him until his vehicle is destroyed. Then pursue the driver on foot until you are prompted to arrest him, and the job is done.
Shortly after, you'll receive a call from Ellie, so go to the Cafe across from the Station. You'll learn the Criminal Scan (which can be used to track down criminal activity in the overworld as well), so scan the shed in the bottom right to find the next robber.
Enter the garden by jumping up the vines left by the farmer, and enter the shed. The Robber will flee, so get after him by moving the box in the shed onto a green platform (just follow the on-screen arrow). Build the LEGO object to begin you pursuit.
Eventually you'll have to free a hose of debris; just follow it around and destroy the objects to continue your pursuit. Then it's the same as the first Robber, just press A when prompted.
Our next destination is the Dockyard of which you began the game at. Jump to the top of the boxes to use the criminal scan again; your target is on the boat.
Run towards the gate, where you'll be asked to use the crates on the Forklift to enter the Gatehouse, simply pull the lever to empty the dockyard.
Talk to the other dock worker to activate a blue investigation point; follow it to locate the Seagull with the sandwich. Take it back to the dock worker, and enter the crane platform to take you up to the ship.
From here, the robber attempts to flee, so just follow him as with the previous robbers to round up this Chapter. Onto the next!
