Theft (simple theft, pickpocketing or theft by trick)
A bag left unattended, a wallet slipped from a pocket, or someone who distracted you with well-chosen words… However it happened, someone took something from you without any right to do so.
There was no threat and no violence : but your property is gone, often without you noticing at the time.
In the street, in a shop, on public transport or even at home, this kind of theft leaves a sense of powerlessness and betrayal. Reporting it helps move things forward.
