British sculptor Maurice Agis has been charged with gross negligence manslaughter over an accident involving one of his sculptures that killed two women.

His inflatable sculpture, Dreamscape, slipped its moorings in Chester-le-Street, in northeast Britain, in July 2006, killing two people and injuring 13.
