Allen, nicknamed Mr. Death or Mr. D, was believed to have been involved in up to 13 underworld murders, including the dismembering of a Hells Angels biker with a chainsaw. He received a ten-year prison sentence for rape during the 1970s. It is also reported that he was a major drug dealer in the Richmond and South Yarra areas of Melbourne during the 1980s.
