Police say six people have been detained on suspicion of seeking to swindle Norwegian banks out of 100 million kroner ($15 million) in a real estate mortgage scam.
Police in the southeastern province of Oestfold said the six face preliminary charges on 65 counts of defrauding or attempting to defraud at least five banks.
The six are accused of faking the value of houses for bank loans and are also suspected of falsifying wage documents and real estate appraisals.
Investigators claim residential houses were repeatedly resold to inflate their value and that two houses may have been subject to attempted arson.
Police did not release the names or any other details about the suspects detained Tuesday.
