An alleged offender incident is an incident involving one or more offences where an individual, business or organisation has been recorded as an alleged offender. An alleged offender incident represents one alleged offender but may involve multiple victims and offences. One incident may involve offences that occur over a period of time but if processed by Victoria Police as one incident, it will have a count of one in the data presented in this section.
There may be multiple incidents within the reference period that involve the same individual, business or organisation as an offender, where this occurs they will be counted for each incident. If there are multiple alleged offenders related to a criminal event, each will have their alleged offender incident counted once in the figures.
Where there were multiple offences recorded within the one incident, the incident is assigned an offence category of the most serious offence in the incident, referred to as the principal offence.
