On Thursday night, a woman involved in the case was released, according to her laywer, but TT reports it is unclear whether she is still a suspect.
The case has two parts - one has to do with tax and accounting crimes, and is being investigated by the Swedish Economic Crimes Authority. That investigation is concerned with six companies, including a cleaning company. The other case has to do with financing terrorism.
Money the men are said to have pulled in via various companies is suspected to have been used to finance terrorism. Newspaper Dagens Nyheter has reported that it was bound for Syria, possibly to go to IS.
The three men deny committing the crimes, according to news agency TT.
