Guys, listen to the details carefully. Abu Trica said they only asked him about a transaction, then they cut him off. This might be some possible reason behind these.
It means EOCO or whatever authorities usually reach out to most of these guys. Anyone who cooperates, could get help. And cooperation can mean many things, like giving them a portion of whatever they received or sharing details so they help gibberish the situation.
In the first place, no one should be able to withdraw such huge amounts from a bank without the bank asking serious questions, unless there are specific banks involved or other arrangements behind the scenes.
Whatever happens to most of these guys in the future will mostly depend on how they choose to cooperate.
