4 people dead, 2 critically injured after lithium-ion battery causes fire at NYC e-bike shop

Four people are dead and two in critical condition after a fire broke out at an e-bike repair shop in New York City Tuesday, authorities said.

The New York City Fire Department responded to the fire at 80 Madison Street at around 12:15 a.m. local time. The fire was caused by a lithium-ion battery on the first floor of the store, the FDNY said in a statement on Twitter.

The FDNY said seven people were injured upon arrival, six of them critically. One firefighter suffered minor injuries.

Of the six people with critical injuries, four later died, including a 71-year-old man, the Office of the Deputy Commissioner of Public Information told USA TODAY. Two “adult females” were in critical condition.

In a news conference, FDNY Fire Commissioner Laura Kavanagh said the fire department has written violations at the location before.

"We have conducted enforcement in this location before," Kavanagh said. "This exact scenario where there's an e-bike store on the first floor and residences above and the volume of fire created by these lithium-ion batteries is incredibly deadly."
