Authorities say a massive blaze that ripped through a Gap Inc. distribution center in New York was intentionally set.
State police say Tuesday that the federal Bureau of Alcohol, Tobacco, Firearms and Explosives determined the origin of the fire was "incendiary."
No other details have been released. State police and the BATF continue to investigate.
The fire late last Monday caused heavy damage to part of the Fishkill facility about 50 miles north of New York City.
Some of the distribution center's 1,300 employees were scheduled to return to work this week in other sections of the sprawling warehouse complex.
The facility serving Gap's northeast region opened in 2000.
