An MP in Finland allegedly cheated parliament out of €13,000 by claiming expenses for a sauna as his second home.
Ville Vahamaki, from the Finns Party, has denied any wrongdoing.
Finnish tabloid Iltalehti reported in July that Vahamaki and another MP had been claiming elevated housing allowances for a sauna in the basement of a Helsinki apartment building.
"In practice, I use it for laundry and so forth," Vahamaki told the newspaper at the time.
He is suspected of having defrauded parliament of around €13,000 in the form of unjustified allowances, the Finnish National Bureau of Investigation said in a statement, adding he had already paid the money back.
The prosecutor will now consider the charges. Police found no grounds to suspect the other MP of a similar fraud.
Finland has a population of 5.5 million people and three million saunas.
