Multiple Jehovah's Witnesses are involved in a health insurance fraud in Germany, with a total amount of loss of ca. 1,3 million Euro.
A 56-year old pioneer 'met the head of the gang at a meeting of the religious group'. He hired her for nursing his grandfather for a monthly salary of 4200 €. After two days, she reported sick - and health insurance had to pay sickness allowance (basically the same amount that she would have earned). After two weeks, she was fired, whereupon she got unemployment benefit. News says that her husband was also a Jehovah's Witness and 'tried to recruit more members for the network in the congregation'.
They played this game multiple times, with several bogus firms etc. Officials finally noticed it when one women was 'hired' for a monthly salary of 134,000 € and got sick immediately after starting, which would have brought her ca. 170,000 € sickness allowance.
