The SEC likely has been investigating FRTD for some time. But as I said, FINRA and the SEC are both regulators. And FINRA often conducts such fraud investigations at the early stage in conjunction with the SEC. Thus FINRA's phone call and 2 hour conversation with the Company 2 weeks ago. They provided the information obtained during the call to the SEC, who determined a trading suspension was warranted.
This is not uncommon with OTC suspensions. FRTD is not in any way unusual.
