Sacha Baron Cohen is being sued by a woman who claims she was left 'crippled' after a physical fracas with his alter ego Bruno at a bingo hall.

Richelle Olson has filed a lawsuit alleging that she is now confined to a wheelchair after Bruno attacked her during a scene for his forthcoming movie.

She claims she was told that Bruno was a celebrity and that he would be happy to call numbers for her charity bingo event she regularly holds in California, reports TMZ. However, Olson was shocked to see that Bruno was an "extreme, outrageous, offensive caricature of a gay man dressed in sexually revealing clothing with an Austrian accent".

When she tried taking the microphone from him after he used "vulgar and offensive" language, Olson alleges that he "offensively touched, pushed and battered" her. His crew is also alleged to have attacked her for up to five minutes in a bid to provoke a reaction.

She claimed that the she sobbed in another room after the incident, only to fall unconscious and hit the floor. She was rushed to hospital, where she was diagnosed as having "two brain bleeds" and has been in a wheelchair ever since.

She is suing Cohen and NBC Universal over the 2007 incident.

Cohen isn't a stranger to lawsuits. He was sued several times by unwitting participants of his hit film Borat. He also caused a stir recently at the MTV Movie Awards by landing bare bottom up on Eminem's face after his flying contraption 'malfunctioned'.
