As previously reported by TMZ, there has been surveillance video of a hotel elevator that appears to show three individuals, presumably rapper Jay-Z, singer Beyoncé, and her sister Solange involved in an altercation.
Presumably, Solange is shown physically attacking the rapper after they appear to exchange words. Beyoncé doesn’t look to get involved in the physical altercation, but does seem to share words.
The security officer also in the video is shown restraining Solange, and stopping the elevator to allegedly break up the incident.
