The people who have been called are told that infection tracking has been done and that they must now do a covid-19 test.
Who has been infected is classified.
The fraudsters say they want to send home a sampling kit to the caller at a cost of 50 kronor.
Then they ask for account numbers.
As the sampling in Halland is free, the region believes that this is a fraud.
They urge the public not to give out account numbers to anyone who calls one.
