The internal investigation is done by the Special Investigations Department, which handles investigations involving police employees. Included in the investigation are representatives from the special prosecution chamber.

- What we have questioned is service failure or abuse and a notification has been sent. Now, the prosecutor will decide whether a preliminary investigation should be initiated and investigate whether any crime has been committed, says Mikael Backman, police area manager in Södermanland.

"May take time"

The policeman seen in the clip has been moved from external to internal service pending the investigation whose task is to look after all the circumstances, hear witnesses and involved parties, which Mikael Backman believes can take time.

- It may take time. We will also review the film to see the overall picture of the arrest. This means that it will be possible to try to clarify the motives behind the action and answer the question why the action looks the way it does.

Possible preliminary investigation

Whether or not a preliminary investigation will be initiated has not yet been decided.

- A message as to whether or not a preliminary investigation will be initiated will probably come here almost immediately during the week.
