Tesla’s CEO Elon Musk is on the hot seat after his personal account was hacked.

The automaker is now under investigation by law enforcement agencies across the country after reports that his personal Twitter account was compromised, the Los Angeles Times reports.

As of Thursday morning, Musk’s personal Twitter feed had been suspended, the company said in a statement.

The Twitter account of Musk, who is the former CEO of SpaceX, also has been suspended.

A Twitter spokesperson said that Musk was notified of the breach and “immediately” took steps to address it.

The company is working to fix the issue, the spokesperson said.

The incident is just the latest in a string of security breaches at the Silicon Valley automaker, which was hacked last month, according to the Times.

Musk’s company was hit with a $20 million hacking penalty by the Securities and Exchange Commission (SEC) in July, according the Times’ story.

The SEC has issued a subpoena for Musk’s emails, which may include emails that he and company executives discussed the breach.

The breach of Musk’s Twitter feed occurred last week, the Times reports, after it was revealed that the automaker had not fully disclosed the extent of the hack in its annual report for the year.

According to the Los Gatos Times, the automakers annual report includes information about the number of cars sold, which it reported as 100,000 in June, down from the company’s 100 million in 2016.

The company’s stock price, however, has plummeted more than 30% in the past two months, to around $2.70 per share.
