The accompanying TMZ report claims that the fracas happened at the Standard Hotel in New York at an after-party for the annual Met Gala, which took place on May 5.
The video, shot from a top-down viewpoint, shows a female figure striking out a male figure, who remains passive. The female figure is then restrained by a second male. Click below to watch.
TMZ claims you can see the bodyguard hit the emergency stop button as the elevator reaches the 12th floor. It further alleges Beyonce was present throughout the attack.
Beyonce, Solange and Jay Z were later photographed walking out of the hotel together, but Jay Z reportedly went to a different car than the two sisters.
A representative for Jay Z has not yet responded to NME’s request for comment.
