There's a lot of juicy information the Feds will get out of Hugo Carvajal as well. He was a "general" who apparently was very close to Chávez and knows a lot about the drug trafficking and money laundering activities that many other high ranking officials in the Chavista hierarchy are involved in. Already the Maduro the administration is ridiculing itself by calling his arrest a crime since Carvajal is supposed to be a "diplomat", but the reality is that his credentials as the consul to Aruba were never approved by the Dutch government, and he traveled there merely as any other Venezuelan citizen, with no immunity whatsoever.
There's a rumor going around now that a lot of the high ranking Chavista officials are starting to cancel their flights to other countries. Could it be they're afraid they'll be "taken in for questioning" as well? I'm just saying, if you got nothing to hide, you shouldn't have to worry about traveling on foreign soil, right? At least soil controlled by US allies, anyway.
