Beyonce's Sister 'Attacks Jay Z In Lift CCTV'
CCTV footage has emerged that appears to show Beyonce's sister physically attacking Jay Z in a lift.
In the video, posted on TMZ.com, a man resembling the hip hop star fends off a series of blows from a woman purported to be his sister-in-law, Solange Knowles.
The scuffle allegedly happened as she attended an after party with the iconic couple at New York's Standard Hotel, following a gala at the Metropolitan Museum of Art.
The hotel said the leak of the video violated the confidentiality it provides customers - and that it would "discipline and prosecute the individuals involved to our fullest capacity".
According to TMZ, the trio entered the lift before Solange began shouting at the 99 Problems rapper - then unleashing a barrage of kicks and punches.
The woman in the video can be seen connecting with a number of blows, despite being restrained by a man thought to be a bodyguard.
As the attack takes place, the man who appears to be Jay Z is seen attempting to protect himself but does not hit back.
Having been pulled away from him, the woman thought to be Solange apparently continues shouting at the rapper and aims at least one more strike at him before they all exit the lift.
Throughout most of the incident Beyonce stands next to her husband and appears to barely get involved, but comes between the pair shortly before they walk out.
All three departed the hotel together, before Beyonce and her sister were reportedly driven away in one vehicle, while Jay Z left in another.
Solange, 27, has achieved moderate success as a singer and model, and was joined on stage by her better-known sister while performing at the Coachella music festival in April.
Sky News has attempted to contact Solange's representative for comment.
