Tesla shares dropped almost 5 percent after Bloomberg News reported that the company is facing a criminal probe over CEO Elon Musk's tweets about taking the company private.

Musk tweeted on Aug. 7 that he was thinking about taking the electric car maker private at $420 and that funding was secured, sending the stock soaring 11 percent, near an all-time high, that day to $387.46. All of those gains — and then some — have since been erased.
