The clip, which was filmed via the hotel’s security cameras, was obtained by TMZ earlier this week and the Standard have already stated that they were taking the matter very seriously.
A spokesman for the hotel confirmed that the employee has been fired, adding that they are now looking at what further action should be taken.
"The Standard has identified the individual responsible for breaching the security policies of the hotel and recording the confidential CCTV video released by TMZ," said Brian Phillips, the hotel's spokesman.
"The Standard has already terminated the individual and will now be pursuing all available civil and criminal remedies."
As the physical attack takes place, a security guard steps between the pair, while a woman reported to be Beyoncé stands still and appears unfazed by the incident.
Beyoncé, Solange and Jay Z are all yet to comment on the clip, though Bey and her sister have been making some interesting updates to their Instagram accounts.
While Solange has removed all but one photo of her sister from her Instagram, Beyoncé filled her feed with four cute snaps of herself and Solange, hinting that the pair aren’t involved in any kind of rift.
Days after the alleged attack, Beyoncé posted a cryptic prayer message on her page, which has been questioned since the video’s release.
