When you're here, quickly take out the cop on the rooftop using your stun gun.
After that, climb on top of the ventilation units and throw gas grenades through the vents.
You can also see a green arrow indicator on top of them. Once you've thrown the gas grenade through all four of the vents, you will get a cutscene of a cop coming out of the police station through the rooftop door and passing out.
Go through the door and take the stairs to the lowest level. When you get inside the police station's main lobby, you need to look for cell keys.
The cell keys can be in several different places and are random every time you play this mission.
The locker room is to the left as soon as you go through the door at the lower level.
Once you've acquired the cell keys, go through the double doors on the left and head down the stairs to the basement.
You will find one or more police officers (depending on whether you completed the optional disruption mission) and continue moving forward and you will come across a computer next to a locked jail cell security door.
Once you're through the door, look behind you as some more cops will show up.
Take them out and then use the cell keys to unlock King Tiny's cell.
Wait for King Tiny to unlock the door ahead and continue moving towards the rear exit.
Head outside through the door and collect your stashed weapons.
After collecting the weapon stash, destroy the control panel by the sliding door.
Then, head back inside the station. Go deeper and stay there until you've lost the wanted level. Yup, that's right. You don't have to run around the city to lose the cops.
Once you've lost the cops, head outside through the rear exit and turn left.
You will find your getaway vehicle stashed not too far away. You can use it to take King Tiny to LSIA.
However, you can use your CEO ability to call in a Buzzard and fly King Tiny to LSIA for a faster mode of transport.
Remember to enter the yellow highlighted area on foot with King Tiny to successfully deliver him to the rendezvous point.
Now, you will have the location of the gang hideout with the main target of this robbery: the Gran Turismo Ommaggio.
Make your way to the gang hideout, which is also a random location every time you do this mission. However, the main mission structure is always the same.
Once you find a window, get inside the vehicle and drive off.
Deliver the vehicle to your Salvage Yard to complete this robbery mission.
With King Tiny freed and the Gran Turismo Ommaggio secured, the main part of the robbery is complete.
Selling the Vehicle
After the robbery's completion, you can either sell the vehicle to Yusuf or salvage it for quick cash. If you salvage it, you will get less amount (20% decreased value).
But if you sell it to Yusuf, you must drive the vehicle to the port. Similar to how you deliver the Simeon vehicles. You get the maximum cash for selling it to Yusuf.
Be careful not to hit the car anywhere as you drive it to the port.
