Bosses at the The Standard Hotel in New York City are investigating how CCTV footage showing an altercation between Solange Knowles and Jay Z was made public.
Management at the venue which hosted Beyoncé Knowles's sister and husband are eager to find out who shared the video obtained by TMZ.
The hotel claimed in a statement they would punish any members of staff who were found responsible for leaking the scenes, which went viral on the internet and across the media.
"We are investigating with the utmost urgency the circumstances surrounding the situation and, as is our customary practice, will discipline and prosecute the individuals involved to our fullest capacity," a representative for The Standard said.
The three-and-a-half minute recording appeared to have been made by someone – possibly an employee or hired event staff with access to the security area – filming a CCTV screen with their mobile device.
A spokesperson added they were "shocked and disappointed that there was a clear breach of our security system".

The blurry video, which appeared to show Solange attacking her brother-in-law, was made on 5 May – the night of the Big Apple's annual Met Gala.
After exiting the Standard Hotel, the two sisters left together in one car, while the rapper left in another vehicle. So far, there has been no comment from representatives of any of the parties involved.
Hours after the footage surfaced, Beyoncé and Jay were pictured courtside in New York, watching their beloved Brooklyn Nets take on Miami Heat. If they were fazed by the arguement being made public, they certainly didn't show it as they put on big smiles.
Beyoncé, 32, looked stylish in a denim jumpsuit and statement heels, while her spouse chose a casual white T-shirt, jeans and a gold chain. The pair shared loving looks and glances, and at one point Jay Z, real name Shawn Carter, put his hand tenderly on his wife's leg.
