The 400 Mawozo is the largest gang in Haiti, mainly based in Ganthier and in the Port-au-Prince suburbs of Tabarre and Pétion-Ville.
[6] According to former Haitian Senator Jean Renel Senatus, who headed the justice and security commission, the group was originally called "Texas" and was known for holding up residents and stealing motorcycles.
[13] On 13 March 2024, YourFellowArab (Addison Pierre Maalouf), a YouTube personality known for touring dangerous places, was kidnapped on his way to interview Jimmy Chérizier.
[18] According to Insight Crime, 400 Mawozo was feared in 2022 because of their innovative methods, in particular "express kidnapping", but also for the "high-powered weaponry, participation criminal economies, and political connections" which permit all gangs to prosper in Haiti.
In 2022, their control of Croix-des-Bouquets extended to the prison, the voting station, and the only route connecting Port-au-Prince to the north of the island.
In addition to truck hijackings, they are involved in smuggling contraband and the traffic of drugs, arms, and people along the border with the Dominican Republic.
