Also, isn't FTX a Bahamian company? Why wouldn't he be there?

And what US crime did he commit, as all the accounting stuff didn't happen in the US, but the Bahamas?

The FTX network of companies (see the consolidated bankruptcy filings) includes more than 100 companies, some of which are American, all of which were ultimately controlled by SBF, most of which had what records they had commingled, and most of which seem to have been tools in the same set of international frauds.

Just tracking down them all, the board of directors, etc...
