A video released by TMZ Monday appears to show surveillance footage of rapper Jay Z being attacked by Solange Knowles, the sister of his wife Beyonce. TMZ says the fight happened last week at the Standard Hotel after the Met Gala in New York.
On the grainy tape, three people can be seen entering the elevator. After what looks like a brief argument, a woman attacks a man, swinging at him and at one point kicking him before she is restrained.
TMZ also posted video of Beyonce and her sister leaving in one car, with Jay Z leaving in a separate one.
In a statement obtained by HLN, the Standard Hotel said that it would investigate the purported leak of the video, which quickly spread online.
"We are shocked and disappointed that there was a clear breach of our security system and the confidentiality that we count on providing our guests," the Standard said. "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."
CNN has not been able to independently verify that the three people on the tape are in fact Jay Z, Beyonce and Solange, nor can the purported location be confirmed at this time.
A representative for Solange Knowles refused to comment and would not verify the authenticity of the tape. CNN has not yet received a response from Jay Z, or Beyonce.
