Prosector Anders Jakobsson told Swedish Radio News on Thursday that several police reports have been filed against Eliasson since the story broke, and that because of this, he will now collect materials to check whether a crime was committed.
Eliasson has told Swedish Radio that he does not believe police broke security regulations when the agency allowed a private company online access to payroll and personnel information.
"We have not acted in violation of the security regulations (Säkerhetsskyddsförordningen). Our view is that we have chosen an alternative approach instead of the defense encryption," Eliasson told Swedish Radio.
Eliasson came under fire on Wednesday after Swedish Radio revealed that he decided, back in the spring of 2015, to forgo using encryption programs approved by the Defense Ministry to keep personnel data safe.
Police said they were in a hurry to get help with their payroll and personnel IT system and that using their own encryption programs would save money. That's why they contacted the Canadian company CGI who developed the system and why they granted them access to such information as officers' names, salaries, addresses and other personal details.
Eliasson admitted that the decision, documentation of which was seen by Swedish Radio reporters, was poorly formulated and gives the wrong impression.
Swedish Radio investigative reporter Daniel Öhman said Eliasson made the final decision to grant the exception that would allow the police to forgo the required encryption programs in sending data to CGI.
Experts at the Defense Ministry said dropping the compulsory encryption programs could jeopardize the data and allow unintended access.
Justice Minister Morgan Johansson said on Wednesday that the Swedish Security Service would investigate the incident.
