The $454 million construction project, which also involves the building of a hotel, office and shopping complex, has been hit with accusations of corruption.
Of the six people charged , Sune Reinhold, a former top civil servant in Solna, was found guilty of accepting payments of $150,000 in illegal compensation.
The money was paid from companies involved in the construction of the arena in the western suburb of Solna in Stockholm. The rest of the suspects, including the former Solna mayor Lars-Erik Salminen, were found not guilty.
Reinhold was given a suspended sentence and ordered to pay $15 000 dollars in fines as well as return the $150,000 in illegal compensation.
The founder of the construction company Peab was among those found not guilty. The company's shares rose by three percent shortly after the verdict was announced.
