The three, two men and a woman, through an assistance company must have received "several million kronor" from the Swedish Social Insurance Agency for alleged help to a woman.
In collaboration with the Swedish Social Insurance Agency, however, the police have been able to see that they did not help the woman during the times for which they received compensation.
The cheating is believed to have lasted for several years and the three assistants were arrested after several months of reconnaissance.
The police are still searching for the woman who was said to have received help.
