Person suspected of an offence. The decision on suspicion and recording is made by the police (or an investigator of the customs or border guard). Only suspects of solved offences are taken into consideration in the statistics.
The main rule is that persons are presented in the statistics as many times as they are suspected of an offence (gross number of persons). The statistical unit used is an offence. If several persons have taken part in the same offence together, the number of offences recorded is one.
If a person commits a series of offences or several similar offences, the number of suspects is calculated based on the offences in this series.
The database tables present the numbers of suspects with three different calculation methods: Suspects of solved offences (or total number), number of suspected offences and according to the principal offence rule/the most aggravated offence.
