A Tesla spokesperson told CNBC that Martin Tripp, an ex-employee who the company is suing for alleged data theft and hacking, may have threatened to attack the company's Gigafactory in Sparks, Nevada.

"Yesterday afternoon, we received a phone call from a friend of Mr. Tripp telling us that Mr. Tripp would be coming to the Gigafactory to 'shoot the place up.' Police have been notified and actions are being taken to enhance security at the Gigafactory."
