Lukas Kamay, the mastermind behind Australia’s biggest insider trading heist, paid $2.375 million for an apartment from TV show The Block with a single trade that took just 25 minutes, while taunting police as they struggled to catch him.

The seller of the apartment, Lysandra Fraser, remembers Kamay inspecting the property on three occasions where he asked about putting a spa on the roof and complained about the microwave being dirty.
