Drive to Vito’s position and talk to him. After the cutscene, you’ll have to chase down Michael Grecco. You can now shoot while driving. You'll also have to deal with Marcano's men that will try to kill you as well. Aim for the tires and when you’re near, shoot. This should disable Grecco and force him to go on foot. Your pursuers can be taken out the same way.
If you weren't able to disable Grecco in time, he'll find the nearest vehicle and try to escape again using that. Once Grecco is out, you can shoot him to disable him. Once disabled, approach him and interact with him to capture him.
However, the job’s still not over. The cops will be all over you so you have to lose them first. After escaping the blue zone, deliver Grecco to Vito’s place to trigger another cutscene and to complete the mission. Now, Vito has regained complete control over this district.
This unlocks the following missions/ conversations:
