There's this article from 2005 (http://www.hotnews.ro/stiri-arhiva-1235758-restituirea-dator...) that mentions the name of the Swedish official, it's in Romanian, Google Translate can help.
He was sentenced to 3 years in prison and got a 3 year ban on business activity for embezzlement, tax fraud and accounting fraud.
Apparently it was Fallenius himself who in court told that the money he took from ABB was going to be used as a bribe, but the court did not agree and sentenced him for tax fraud instead. See http://www.svd.se/abb-direktor-domd-till-fangelse , (Swedish)
