I don't think anyone has actually been arrested. The exchange office was raided in a surprise move, so as to determine the true nature of the company's operation. It may very well be that nothing comes out of this.
Although, there has been no activity on any of the company's social channels. One would expect something like this to garner some social media attention, but either it hasn't, or its all being removed. Its also possible that the company turned out to be a real scam.
At present, we believe that this is a violation of foreign exchange regulations of the country. If we are able to establish money laundering aspect then he can be arrested
In any case, the above line clearly states that the website owner has not been arrested.
