Hong Kong (CNN Business) Tesla is investigating after one of its vehicles appeared to explode in China.

Weibo WB short video of surveillance footage posted on Chinese social media siteshowed white smoke emerging from what looks like a white Tesla car parked at a lot in Shanghai. After a few seconds, the electric vehicle bursts into flames and the clip ends soon afterward.

The video, which was filmed just after 8:15 pm local time on April 21, appears to show a Tesla Model S sedan. It was posted on Chinese social media a couple of hours later and has since been shared widely.

Tesla TSLA would not confirm any of the details, other than to say it is investigating the incident alongside Chinese authorities.

"We immediately sent a team on-site and we're supporting local authorities to establish the facts. From what we know now, no one was harmed," a Tesla spokesperson told CNN Business on Monday.
