(Reuters) -An electric truck which was previously damaged reignited at Nikola's Phoenix, Arizona headquarters on Sunday afternoon but there were no injuries, the company said, sending shares down about 4% on Monday.
Nikola had reported a fire last month around its headquarters and said it suspects foul play behind the incident that affected multiple trucks.
"At approximately 2 pm today at Nikola HQ, one of the trucks that was previously damaged reignited. No one was injured and the fire was quickly contained," the company said.
The damaged trucks were kept at the company's Phoenix site for "safety monitoring and the ongoing investigations."
Earlier this month, Nikola said it will liquidate the assets of Romeo Power, an EV battery maker it acquired less than a year ago for $144 million. It had warned the move was in the offing in May.
The company reported in early July that retail sales of its trucks doubled to 66 in the second quarter, while the wholesale figure rose to 45 from 31.
