If what has happened is punishable, the police will investigate it. If they arrest the perpetrator of the violence, then the perpetrator will go to the police station. The police will carry out further investigations into the circumstances of the violence and any criminal offenses. The public prosecutor will decide whether the perpetrator of the violence is to be brought before a judge or allowed to go home with a summons. The mayor — or, on their behalf, the assistant public prosecutor — may impose a restraining order on the perpetrator of domestic violence. In that case, the perpetrator of domestic violence may not enter his or her home for 10 days. During this period he or she is also not allowed to contact the victim and any children involved. During this cooling-off period, the necessary assistance can be provided for all those involved and further escalation can be prevented. After these 10 days, the mayor can extend the house ban to a maximum of four weeks. Domestic violence perpetrators can be prosecuted and possibly sentenced to imprisonment. For assault, the sentence can even be increased if a family member is involved. Where no report been made, the police, together with the Public Prosecutor's Office, will endeavor to prosecute the case ex officio. This means prosecution without the victim having made a report.
