David Toska, the confessed mastermind of the robbery, was sentenced to 19 years in prison on Friday.

His sentence was considered somewhat surprising as several of the co-accused received the stiffest penalty possible, prison plus preventative custody, a sentence that can amount to life imprisonment since it allows for extended isolation from society.

Toska's sentence indicates that he received a 'discount' for confessing and recounting his role in the crime in detail. The prosecution had pressed for a maximum sentence for Toska, arguing that his refusal to give information about any of the others involved in the crime showed his enduring loyalty to criminal circles.

Kjell A. Schumann, Metkel Betew, Ridvan Halimi and Thomas Thendrup received 16 year sentences plus preventative custody, with a minimum sentence of ten years served. The prosecution had hoped to get 18-21 years plus preventative custody.

The NOKAS case is the most expensive investigation and most discussed crime in Norwegian history, with nearly 40,000 newspaper and online articles on the heist, investigation and trial.
