The moving floor immediately turned off, but unfortunately it was too late. The child had already suffered severe head trauma.
He was taken to Grady Hospital after the incident around 3:30pm, and was later pronounced dead.
"There was a tragic accident at the hotel involving a young boy," Westin Peachtree Plaza Manager George Reed said in a statement obtained by the AJC.
"Words cannot express the depths of our sorrow. Our thoughts and prayers are with his family."
The Sun Dial is said to be closed until further notice, and an investigation is being conducted by the Occupational Health and Safety Administration.
The boy's death comes just a year after a kitchen employee at the same hotel died after getting accidentally locked in a freezer overnight.
The 61-year-old woman, Carolyn Robinson, had worked with at the Westin hotel for more than 35 years.
Less than a month after that, ten-year-old Stephen Akinlabi died at the hotel's pool after he fell in at a birthday party.
