It's an island. Tough to get off even if not arrested. I'm sure if he tried to get on a plane all kinds of "problems" would have appeared (computer not working, ...) If he tried a boat, "oh look, it's leaking oil, we can't let it leave and pollute the waters".
Bahamas will have absolutely not let him get out of their sight. They have so much egg on their face.
I can even see the titles if he left "Did he bribed Bahamas officials to look the other way?" ...
