Multiple concept cars were burned and a hazardous materials crew was called to Pasadena after a General Motors design facility housing lithium-ion batteries caught fire on Wednesday night.

The four-alarm fire broke out at around 5:45 p.m. in the building located on Sierra Madre Villa Avenue, according to the Pasadena Fire Department.

The cause of the fire remained under investigation late Wednesday as crews continued to battle the fire, which was complicated by the presence of lithium-ion batteries inside the building. It's unclear if the batteries were being stored inside or if they were a part of the cars being developed by the company.
