TMZ has released surveillance video which allegedly shows Beyonce’s sister Solange attacking Jay Z in an elevator.

It has been reported that the incident occurred at a Met Gala after-party in the Standard Hotel in New York last week. After a group enters an elevator – which includes Jay Z, Beyonce and her sister Solange, and another man – Beyonce’s sister begins attacking Jay Z, who does not fight back, other than grabbing the woman’s foot as she tries to kick him.

The unidentified man in the elevator grabs Solange, and presses the emergency stop button. Beyonce does not intervene in the altercation.

After the incident, the two women were seen leaving together, while Jay Z was taken by security to his SUV.
