Abraham Gilbert Saffron was a successful Sydney businessman who hated his nickname and spent a fortune trying to have it expunged from the record by threatening anyone who used it publicly. The name was Mr Sin and it was well deserved. He built a vice empire on a triangular business model – the three points were bribery, blackmail and arson. He organised sex, often with under-age boys and girls, secretly photographing patrons to use against them.  He paid bribes to police - $750 per club for local police and $5000 a week for senior police and was so brazen he repeatedly visited the bent Deputy Commissioner Bill Allen at headquarters. Six of Saffron’s many properties caught fire between 1980 and 1982 - all deliberately lit.  On June 9, 1979, the ghost train at Sydney’s Luna Park was engulfed in flames, killing six children and the father of one of them. It was a property Saffron wanted to own. The police investigation was a disgrace, not because of incompetence but corruption. Saffron said he wasn’t involved but he would, wouldn’t he?   Become a subscriber: our supporters power our newsrooms and are critical for the sustainability of news coverage.
