Östgöta Correspondent was the first to tell.

- Regardless of which person it is, it is very unfortunate that this type of information is out in public, says Rickard Lundin, Security Manager Region Östergötland, to SVT News East.

He says that an internal investigation will now investigate whether someone in the Östergötland region has illegally taken part of this information.

- We currently do not know how this individual has accessed these journal entries, where this information comes from, says Rickard Lundin, adding that this is exactly what should be investigated now.

Do you think your system is secure?

- As a patient, you should feel confident that it is safe. We have zero tolerance for what we call unauthorized access, says Rickard Lundin.

On Tuesday, police arrested a 37-year-old man suspected of the 2004 double murder. The man admitted on the same day that he was behind the act. The case has received a lot of attention in social media and a journal copy, relating to the suspected man, has leaked online. These are documents that are covered by strong patient confidentiality.
