Les Cleveland who was in Opera Company productions with David talked about David’s “black side” and said David really ‘got off” on the evilness of one of his (Les) characters and seemed unable to differentiate between someone acting the part and being the person. He also said David knew of Laniet’s activities because he had heard fellow performers mentioning their association with her and he became enraged by this.  Les spoke to a magazine sometime after David's arrest and mentioned that David “had quite a paddy”.  He never gave evidence in Court.
