A police officer can also arrest you on their own initiative if they think that there is a reasonable suspicion that a crime has been committed. If you have been arrested by a police officer who had a reasonable suspicion that you have committed a crime, you need to have a formal interview or förhör at the police station as soon as possible. Friends and relatives of people who have been arrested can also contact their embassy for them, so that the embassy can find out where they are being held and any details of the suspicions against them.
