Long time AC/DC manager Crispin Dye was brutally attacked and robbed on December 23, 1993.  He died on Christmas Day, two days later.

Dye was in Sydney, Australia celebrating the release of his own album.  An eyewitness saw three men standing over him riffling through his wallet in the early morning hours of December 23, 1993.

Now, over 20 years later, New South Wales, Australia Police Minister Stuart Ayers has announced a $100,000 reward for information leading to the arrest and conviction of those responsible for his death, according to the Sydney Morning Herald.

Detective Superintendent Mick Willing said, "There are people out there who know those responsible for Mr Dye’s death and we’re hoping this reward may prompt them to get in touch with police."

Dye had worked with AC/DC for the past seven years, a period in which the band became one of the world's biggest rock bands.
