An electrical wiring problem likely caused the fire that damaged a massive swath of New Jersey's boardwalk last week, which had been freshly rebuilt after Superstorm Sandy wrecked it last October, authorities said Tuesday.
An investigation ruled out human involvement in the fire.
Hundreds of firefighters worked for nine hours before getting the fire under control Thursday night.
Dozens of businesses were destroyed in the fire, Gov. Chris Christie told reporters Friday.
Officials earlier noted that other structures were damaged when winds carried embers from a frozen custard shop, where they believe the fire started, up the boardwalk to a condominium complex, pier and an arcade, city and county officials said.
On Saturday, business owners met with Christie in a closed meeting to discuss the future of the boardwalk. Christie announced an initial $15 million in aid to help rebuild.
