A fire at a New York City e-bike shop quickly spread to upper-floor apartments and killed four people early Tuesday in the latest deadly blaze linked to exploding lithium ion batteries.
The fire, reported shortly after midnight, happened at a shop that was cited last summer for safety violations related to the storage and charging of batteries, officials said. Investigators determined that it was an accident caused by a lithium ion battery, which can overheat while being charged and explode in an intensely hot flare of flame, fire officials said.
