After Jordi calls you, immediately leave the prison. You must do this before the police arrive at the entrance. After leaving the building, immediately go to the right, run downstairs, and enter the car. Drive out of the parking garage and travel to the nearby train station. Once there, hack a train. If a train is not available, run on the rails until find one, but avoid the helicopter. Having the Helicopter hack will help, as it will continue to follow you even after you are riding the train before eventually giving up the chase.
