Elon Musk is once again back in the news for his erratic tweets on the company's financial performance, as a Tesla investor has sued him and the board of the company for violating a settlement with the US Securities and Exchange Commission (SEC) that barred Musk from tweeting on the sensitive financial information related to the electric car maker.

The lawsuit claims that Musk is exposing Tesla to potential penalties from regulators and could drive down its stock. Musk's "erratic" actions have caused the company "substantial damage", including billions of dollars in lost market capitalisation, reports TechCrunch, citing the lawsuit. Tesla did not comment on the lawsuit.
