Western Uusimaa district court has handed down prison sentences to two men convicted of multiple rapes of children aged between five and 15.
The worst case involved a child drugged and raped for ten hours, according to a statement from the National Bureau of Investigation (NBI) investigation lead Sanna Springare last year.
Court proceedings were held behind closed doors and the court records were sealed, although the verdict is public.
A former parish councillor and travel industry entrepreneur aged 59 was convicted of two counts of child sexual abuse. The court ruled that the man's actions were sexual in nature and damaging to the victims' development.
The second defendant, aged 51, was convicted of two counts of aggravated sexual abuse, keeping indecent images of children and narcotics crimes.
Both men received prison sentences of one year and eight months, and were told to pay compensation of between 1,750 and 6,000 euros plus court costs.
The same two men are also accused of a series of similar crimes in South Ostrobothnia. Yle is not naming them at this stage.
The verdict in that case is due to be handed down on 17 December.
The NBI announced in 2019 that it suspected several Finnish men of involvement in violent sexual abuse of children, and producing images and videos of their crimes.
Police confiscated some 400 hours of illegal video material, some of which was played during the trial. Police say that some of the material depicted especially cruel acts.
The victims were all boys aged between five and 15 when the crimes took place. The crimes themselves were committed between 2004 and 2014.
