Microsoft's recently acquired Fast Search & Transfer was charged on Thursday with accounting fraud by Norwegian officials, Reuters reported Thursday.
According to the Reuters report, police raided Fast's offices in Oslo in order to preserve evidence.
Microsoft didn't mention the charges in a statement, but it confirmed that police showed up at its offices Thursday.
"We can confirm that the Norwegian Police for Economic Crime this morning conducted inquiries at Fast's offices in Oslo," the software maker said in a statement. "Microsoft and its subsidiary Fast Search & Transfer (are) cooperating fully with the police inquiries. We are not in a position to make any further comments at this time."
Fast, which specializes in enterprise search, was acquired by Microsoft earlier this year for $1.2 billion.
