The 41-year-old, 37-year-old and 30-year-old are active in several limited companies in Norrköping.
The 43-year-old has previously appeared in several bankruptcies in Norrköping.
None of them have been convicted of any financial crime before.
The crimes they are suspected of must have taken place during the years 2016 to 2018.
- It is mainly about crimes committed in Norrköping, says Cecilia Danielsson, acting deputy chief prosecutor at the Economic Crimes Chamber in Linköping.
Otherwise, the prosecutor is very secretive about the circumstances.
- I can not comment on anything more about this at the moment, she says.
The men are detained with restrictions. The district court decided that prosecution should be brought or an extension of prosecution requested no later than 29 October.
