"The preliminary investigation is still ongoing and the suspicions against the two persons have been strengthened," said chamber prosecutors Henrik Wallin and Rickard Finnberg in a press release.

They continue:

- The reason for the decision to release the suspects on a free basis is that the preliminary investigation has entered a stage where the investigation can now be conducted with the suspects on a free basis. The investigation is taking place at an undiminished rate and a large number of investigative measures remain, says the prosecutors Henrik Wallin and Rickard Finnberg.

Prosecutors say in a press release and state that they are not currently available to the media for further comment.
