On October 24, the Federal Police of Brazil executed six search and seizure warrants in São Luís and Timbiras as part of Operation Cold Stones, aimed at uncovering potential fraud in a bidding process for the purchase of office supplies by the Timbiras City Hall. This operation is a response to allegations of impropriety in the use of federal resources intended for public education and health services.

The investigation focuses on the misuse of funds from several federal programs, including the Fund for the Maintenance and Development of Basic Education and the Valorization of Education Professionals (Fundeb), the National Health Fund (FNS), and the National Social Assistance Fund (FNAS). Documentation and approximately R$ 122,000 in cash were seized during the operation, indicating a serious breach of trust within local governance.

The warrants were issued by the Regional Federal Court of the 1st Region (TRF-1), demonstrating the judiciary's involvement in overseeing the legality of administrative actions involving substantial federal funding. The outcome of this investigation could have severe implications for local officials in Timbiras, highlighting ongoing concerns about transparency and accountability in public procurement processes in Brazil.
