From what I've read today sounds like the company went broke and so investors lost their money. Apparently Alan Ikin got knocked back some bank loans to complete building new storage facilities in Townsville and Toowoomba or something (he was talking about that 5 years ago) and so the business went bust.
How that makes him a crook I don't know. Sounds to me like it's just bad luck, and perhaps he got some bad advice about expanding the business.
Alan Ikin himself has lost his home, he's gone back to driving a truck, his wife's had to go back to work and Alan has had to borrow Ben's car. He's pledged to repay everybody who's lost their money.
To me it just sounds like a hard luck story.
So yeah if ACA wanted to make it sound like Alan Ikin had done the dirty on people, then I can fully understand why Ben would tell them to get stuffed.
