A Syrian refugee handed in 150,000 euros to police - after finding the cash in a wardrobe that had been donated to him.
The 25-year-old, named only as Muhannad M, had only recently moved into his new flat in Minden in Germany's north Rhine-Westphalia when he made the discovery.
Police say he was assembling a cupboard he had been given by a charitable organisation when he came across the money.
He found about 50,000 euros in cash as well as savings books containing more than 100,000 euros hidden under a board.
Police said in a statement that while small amounts of money are regularly handed in to authorities, 'such a large sum is the absolute exception.'
he man arrived in Germany last October as a refugee - though his family are still believed to be in Syria.
According to Yahoo, the refugee told German newspaper Bild that the money was all new 500 euro notes and at first he thought they were fakes.
After checking the internet to find out whether they were real, he decided that they were before informing migration authorities.
He said: 'Allah would never allow me to finance my own interests with someone else's wealth.'
Police are attempting to track the rightful owner of the money.
A spokesman is quoted as saying: 'This young man has acted in an exemplary way and deserves great respect.
'It sometimes happens that smaller amounts of money are handed in. But this kind of money is the absolute exception.'
It has been reported that Muhannad will receive 3 per cent of the cash as a finder's fee.
