The Norwegian police economic crimes unit has charged Microsoft-owned search technology firm Fast Search & Transfer with accounting fraud, reports Reuters.
"We raided Fast's offices to secure evidence," police attorney Baard Thorsen said. "The charge is for accounting fraud."
Fast was acquired by Microsoft for $1.2bn this February.
"The charge regards accounts from before Microsoft came in," said Thorsen. "We think Fast recognised revenues that there is no basis for."
Fast is a major provider of enterprise search software. Fast has made no comment on the raid.
