The appeals court in Oslo boosted the prison term initially handed to Petter Tharaldsen from eight years to nine-and-a-half. Tharaldsen is believed to have driven the getaway car that later was found torched.

Bjørn Hoen, charged with being the main organizer of the Munch robbery, was handed a nine-year jail term, up from the seven years he'd been sentenced to by the lower court. Prosecutors had sought 11 years for him.

Stian Skjold, who police believe was one of the two men brandishing weapons who actually charged into Oslo's Munch Museum and tore the Munch paintings from the walls, had been acquitted by the lower court but was sentenced on a minor drug conviction. The appeals court ended up handing him a five-a-half-year jail term.

The other armed robber is believed to have died of a drug overdose before the case went to trial.

The appeals court also ordered the men to pay around NOK 1.5 million in damages, mostly because of their apparent disregard for the value of the paintings and for endangering them. The money is meant to help pay for repairs.
