The warehouse serving as the barracão for the Mocidade da Ilha samba school in São Luís experienced a partial roof collapse, injuring five individuals. The local government had closed the building since January 14 after a structural inspection revealed serious visible problems with the property. José Lisboa, a lieutenant colonel of the Fire Department, confirmed the long-standing closure, emphasizing that the building's occupation was irregular, and the closure had been officially communicated to the relevant parties.

Residents of the area noted that the building, formerly known as Clubão da Cohab, belongs to a neighborhood association and had been granted for the samba school's use. Oscar, the operational director of the samba school's operating group, expressed disbelief at the incident, indicating that they did not anticipate the roof collapsing. He denied any claims of invasion, defending their right to use the facility and highlighting the unexpected nature of the structure's failure despite its prior condition.

This incident raises significant safety concerns regarding the accountability of both the local government and the samba school in addressing building inspections and maintenance. While the Fire Department's action to reinforce the closure aimed to prevent further occupancy, the injuries sustained during the roof collapse call into question the adequacy of prior inspections and the communication of hazards to the community, necessitating a thorough investigation of the circumstances that led to this dangerous situation.
