The trio had been going down in the elevator in a block of flats in the city of Changsha, Hunan Province,
China, when it came to an unexpected halt on the fourth floor - before suddenly dropping just seconds later.
The end of the clip then shows them on the floor as they tended to their injuries. Li, one of the passengers, described only suffering minor bruises to his leg, while another received treatment for two fractured lumbar bones. The status of the third passenger is not currently known. Li said "Everything was spinning. We were all thrown in the air before crashing onto the floor.”
