A city in Germany has discovered that Sudanese refugees have been scamming taxpayers out of millions of dollars through welfare fraud.

The city of Braunscheig discovered over 300 cases of welfare fraud, most of which involved Sudanese refugees, German press reported Sunday. The cost is estimated to be around 3 to 5 million Euros, or between $3.2-5.3 million.

Scamming welfare officials was not difficult for the asylum seekers, as they grew beards, wore glasses, and changed hairstyles to trick them.

German officials estimate that on average, the fraud per person reached thousands of Euros. One asylum seeker used around 12 different identities in his scams.

These refugees are believed to have arrived in 2015 during a massive flow of migrants into Germany.
