The "Aigrefeuille d'Aunis" police unit works together with that of "Surgères" where two units of the police force coordinate their efforts within the Community brigades of Surgères and Aigrefeuille, known under the acronym "COB Surgères / aigrefeuille". This unit operates in two cantons together with over 28,000 inhabitants and covers 23 communes. "COB Surgères / Aigrefeuille" is empowered to conduct anti-crime operations (ADO) with stop and search for people and vehicles, occasionally assisted by additional anti-narcotic units (air support helicopter, dog and patrols from the Psig of Rochefort).
