SpaceX founder Elon Musk listens at a press conference following the first launch of a SpaceX Falcon Heavy rocket at the Kennedy Space Center in Cape Canaveral, Florida, U.S., February 6, 2018. CNBC posted what it said was a copy of the email in which Musk said the sabotage included the using of false usernames to make changes to the code used in the Tesla Manufacturing Operation System, as well as "exporting large amounts of highly sensitive Tesla data to unknown third parties".
The full extent of his actions are not yet clear, but what he has admitted to so far is pretty bad. Musk said this month that Tesla had worked through numerous issues.
Sunday's memo was followed Monday morning by Musk alerting staff to a fire a day earlier in what he referred to as the "body-in-white production line". While a spokesman declined to comment, an employee who asked not to be identified confirmed he received the email.
"As you know, there are a long list of organizations that want Tesla to die", he wrote.
Now, CNBC has learned that Musk also sent an e-mail to all employees at Tesla late on Sunday night alleging that he has discovered a saboteur in the company's ranks.More news: Senate Panel Holds Hearing on DOJ Inspector General Report
"As you know, there is a long list of organizations that want Tesla to die", Musk wrote, mentioning Wall Street short-sellers, oil and gas companies and rival vehicle manufacturers, but naming none. Production has resumed and there were no injuries or significant equipment damage, she added.
Last week, the Palo Alto-based automaker said it was cutting about 9% of its workforce - about 3,600 mostly white-collar employees - in an attempt to become profitable.
Musk said the reorganization did not affect hourly assembly-line employees and was not expected to delay manufacturing targets. However, Tesla's stock price has rallied almost 17 percent since the company's June annual shareholder meeting where Musk promised profitability in the third quarter.
Tesla has faced plenty of criticism about its ongoing troubles in ramping up Model 3 production.
