(Reuters) - General Motors (NYSE:GM) said on Wednesday a fire at its Factory Zero Detroit-Hamtramck was likely caused by a forklift accidentally puncturing a container with battery materials, according to the automaker's initial investigation.
The fire, which broke out on Tuesday, halted production for the day at the plant, and General Motors said its investigation on the incident continues.
The automaker had previously said no employees were injured in the fire which occurred at the plant's shipping dock area.
The Detroit plant assembles ultium battery-based vehicles, including the GMC HUMMER EV Pickup and SUV.
