NEW YORK (CBSNewYork) -- The iconic Macy's flagship store in Herald Square reopened Saturday morning, as an investigation into a fire at the store continued.
The flames could be seen from outside, and inside, there was confusion and chaos as shoppers were surrounded by heavy smoke.
"I was eating, I was shopping. Everything broke loose," shopper Biro Marius said.
"Everyone was carrying on as normal and then smoke started rising up. Twenty or 30 trucks showed up," Frasier Smith added.
The blocks surrounding the flagship store were blocked off. Officials said a small mechanical fire in the basement got into the vents, and filled the iconic building with smoke.
Macy's said the fire was mechanical in nature. No injuries were reported.
The store was reopened at 10 a.m. Saturday.
The well-known department store occupies more than 1 million square feet of retail space.
