Art dealer Hillel ‘Helly’ Nahmad, the high-profile owner of the Helly Nahmad Gallery in New York, has been named on a list of people charged with running an illegal gambling business.

The indictment from the Manhattan Attorney's Office names 34 defendants who are alleged to be members or associates of two connected organisations that have been the subject of a complex undercover investigation by the FBI's organised crime unit.

Mr Nahmad, 34, pleaded not guilty when he appeared in court last month. A trial date has been set for June 2014.

None of these charges relate to Mr Nahmad's cousin (also named Hillel) who runs the Helly Nahmad Gallery in London's Cork Street.
