Although much of what constitutes bullying is not regarded as a crime, some bullying does involve violent or illegal acts. In such cases schools are required to report to the relevant Department of Education and/or to the Police. What constitutes a crime, eg., regarding the abuse of cyber technology, may vary from place to place. Hence schools need to be informed on what acts of bullying by students should be reported and to whom.
Establishing and maintaining close relationships with the police is important for schools as they can help both proactively and reactively. A comprehensive account of what roles the police can play in the United States is available in a report provided by the US Department of Education (2011) Analyses of State Bullying Laws and Policies. www2.ed.gov/rschstat/eval/bullying/state-bullying-laws/state-bullying-laws.pdf
