The territorial strategy for delinquency prevention was officially adopted during a plenary session in Tremblay-en-France, bringing together key stakeholders such as Mayor Virginie De Carvalho, the sub-prefect of Seine-Saint-Denis, the public prosecutor, the departmental councilor, and the academic directorate of National Education. This meeting allowed for a review of previous years and the presentation of the local security diagnosis.
In 2025, positive developments were observed, including a decrease in burglaries, car thefts, and smash-and-grab thefts. Rates for several categories of violence and burglaries remain below departmental averages. However, between 2023 and 2026, an increase in intentional physical assaults was noted, while property crimes remained generally stable. Vehicle and accessory thefts continue to be an area of concern.
For the next three years, the strategy is structured around three complementary axes. The first aims to better identify the needs of young people and prevent risky behaviors through educational success pathways, citizen projects, and school interventions. The second axis strengthens social cohesion, victim support, and the protection of vulnerable individuals, mobilizing devices such as support for women victims of violence and the presence of a social worker at the police station.
The third axis focuses on coordinating territorial actors, calling for increased cooperation between the municipal police, video surveillance, local urban and social management, landlords, shopkeepers, and the National Education system.
“"I make security one of the absolute priorities of my mandate, because the Republic must respond firmly to those who break the law."
Virginie De Carvalho also emphasized that insecurity constitutes "fundamentally a social injustice" and reaffirmed her commitment to ensuring a peaceful, open, and respectful city for all residents.
