NEW YORK — The Standard Hotel in New York City says it is investigating the leak of a security video that appears to show Beyonce Knowles' sister, Solange, attacking Jay Z.
Asked about the video on Monday by the Associated Press, the hotel issued a statement saying it is "shocked and disappointed that there was a clear breach of our security system."
TMZ posted the video of the star singers and said it was shot last week inside a Standard Hotel elevator. It appears to show Solange attacking Jay Z in Beyonce's presence. Jay Z and Beyonce were married in 2008.
A security guard intervenes. There is no audio.
The hotel says the leaked video violates the confidentiality it provides customers. It says it "will discipline and prosecute the individuals involved to our fullest capacity."
Representatives for Beyonce, Jay Z and Solange didn't immediately comment.
