The way British socialite Ghislaine Maxwell is being treated in a New York jail is "degrading" and "amounts to torture", her brother has said.
Ian Maxwell said she was being held under constant surveillance in a 6x9ft (1.8x2.7m) cell with no natural light, and the food was "basically inedible", reports the BBC.
Maxwell is accused of helping the convicted sex offender Jeffrey Epstein groom young girls, which she denies.
She is currently seeking bail, ahead of her trial which is due in July.
Prison officials have not commented on her conditions.
Maxwell, 59, who also has US and French citizenship, has been in jail in Brooklyn since she was arrested last July at her secluded mansion in the state of New Hampshire.Her two previous applications for bail were unsuccessful, with prosecutors saying she was a flight risk.
On Wednesday, Gloria Allred, a lawyer representing the alleged victims, told the BBC that bail "should be out of the question, it would be very upsetting to the victims".
