In Shanghai, China, two people were killed on Wednesday after the car they were in, for an unknown reason, crashed into the facade of the third floor and ended up in the street. Passengers did not survive that blow, and it became known on Friday.

The accident occurred at the building of the Chinese electric vehicle manufacturer NIO. It is not entirely clear what exactly was on the third floor. The reports are rotated between the showroom and the test center. In the car were an employee of NIO and an employee of a partner of the company.

NIO said in a statement that it is cooperating in the investigation into the cause of the accident. At first, the company was quick to say it wasn’t the same car. This led to a firestorm of criticism on Weibo, the Chinese counterpart to Twitter. The message was later edited.

NIO is a new Chinese brand established in 2016. The first deliveries started a year later. The brand now has branches in London, Munich and San Jose, California. Sales started in Norway last year and the brand may also come to the Netherlands in the near future.
