An elevator surveillance video appears to show singer Solange Knowles, younger sister of music star Beyoncé, pummeling her brother-in-law Jay Z and continuing to kick him after being pulled away.

TMZ.com, which posted the silent footage Monday, said the video was shot at Manhattan's Standard Hotel following a party May 5, after the annual Costume Institute Gala at the Metropolitan Museum of Art. Rapper and music mogul Jay Z, his wife Beyoncé and Solange Knowles enter the elevator along with an apparent bodyguard. Within seconds, Knowles begins screaming at Jay Z and hitting him. The apparent bodyguard wraps his arms around Knowles, 27, and pulls her away, but the singer continues flailing and at one point kicks Jay Z, 44.

The man holding Knowles can be seen hitting the emergency-stop button once the elevator reaches the 12th floor. Beyoncé, 32, standing near Jay Z at the back of the elevator, avoids the confrontation.

In a longer video TMZ posted later, the man releases Knowles after a full minute. When the elevator reaches the lobby Knowles attacks Jay Z twice more, with Beyoncé finally inserting herself between the two.

All left the hotel together, TMZ said, adding that Beyoncé and her sister entered one car while a security person walked Jay Z to different vehicle.

Representatives for Knowles, Beyoncé and Jay Z did not immediately return requests for comment.

The Standard issued a statement Monday saying it is "shocked and disappointed that there was a clear breach of our security system" in letting the video get out and it "will discipline and prosecute the individuals involved to our fullest capacity."
