Lawyers for a British tourist who says he was badly hurt taking part in an illusion by Las Vegas headliner David Copperfield in 2013 say they’ve found three other people who were injured in shows over the years.

Lawyer Adam Deutsch told a judge on Wednesday that each is willing to testify before a jury that has heard Copperfield and the show’s executive producer deny knowing of anyone being injured during more than 15 years performing the signature vanishing act.

Mr Deutsch said the three, all women, came forward after hearing about Copperfield’s testimony in the ongoing negligence trial.

Judge Mark Denton ruled that before they testify, the women should be questioned under oath by defence lawyers for Copperfield, the MGM Grand resort and several corporate entities facing civil damages claims.

Gavin Cox, from Kent, alleges he fell after being hurried by stagehands through an alleyway coated with a powdery residue near a large rubbish bin.

He is claiming lasting brain and bodily injuries from his fall have cost him more than 400,000 US dollars (£286,000) in medical care.
