Elon Musk sent an all-staff email on Sunday alleging "extensive and damaging sabotage" by a Tesla employee that the company will investigate this week, according to CNBC.
The person in question changed the code of an internal project and exposed data to third parties, according to the CEO's email.
"The full extent of his actions are not yet clear, but what he has admitted to so far is pretty bad," Musk wrote, adding that the unnamed employee supposedly took action against the company after being passed up for a promotion.
He went on to say that there "may be considerably more to this situation than meets the eye," noting that “there are a long list of organizations that want Tesla to die.” Musk listed “oil & gas companies” and “Wall Street short sellers” as being among the company's potential enemies.
Last week Tesla announced it would lay off 9 percent of its workforce as part of corporate restructuring.
The automaker is ramping up efforts to meet its goal of producing 5,000 Model 3s, the company's attempt to offer a more affordable car that would allow it to break into the broader consumer market.
