Alleged offender incidents

An alleged offender incident is an incident involving one or more offences to which an individual, business or organisation has been linked 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. 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, known as the principal offence.

The number of offender incidents involving a male increased in the year ending March 2017 by 9.9% (13,040 incidents) from the previous year. Incidents involving a female offender increased by 10.9% (3,528 incidents) from the previous year.

2.3 Number of alleged offender incidents by principal offence category

In order to best represent the type of offence associated with an incident involving multiple offences, the most serious offence within an incident is determined and this becomes the principal offence to represent the incident.

By principal offence, the category that made up the largest proportion of offender incidents was Property and deception offences. These offences made up 38.6% (69,863 incidents) of all offender incidents, which was a 17.0% (10,159 incidents) increase from the previous year.

Alleged offender incidents by principal offence, April 2014 to March 2017

In the past three years, the number of alleged offender incidents with a principal offence of Crimes against the person has been steadily increasing. In the year ending March 2017, Crimes against the person made up 26.4% of all offender incidents.

Incidents with a principal offence of Drug offences have remained unchanged in the past year comprising 14,721 alleged offender incidents. This offence division made up 8.1% of all offender incidents.

Offender incidents with a principal offence category of Justice procedures offences rose in the past three years to 27,014 in the year ending March 2017. This was driven by increases in incidents involving a breach of family violence order, resist or hinder officer and those involving a breach of intervention order. In October 2013, two new offence codes came into effect resulting in a large increase for breaches of family violence orders leading to an increase in these incidents.

2.4 Outcome

As at 18 April 2017, over a third (40.4% or 73,174) of all offender incidents recorded in the year ending March 2017 resulted in an Arrest, while 48,218 (26.6%) resulted in a Summons and 35,681 (19.7%) in an Intent to Summons being recorded. There were 10,035 (5.5%) offender incidents where a Caution or Official warning was issued.

An Intent to Summons is an interim investigation status and is not necessarily the final outcome of an incident. As the data is captured at a point in time, the investigation status of each incident is subject to change.
