Through ‘Operação Quíron’, the Maranhão State Civil Police investigated allegations of embezzlement, extortion, and criminal association. This operation led to the 90-day suspension of Regional Delegate Cleosnaldo Brito Sirqueira Júnior and the seizure of firearms, ammunition, and electronic devices during searches in Grajaú and Barra do Corda. The investigation also involves a police investigator, a municipal guard, and an administrative employee. Separately, the Court of Justice of Maranhão (TJMA) issued a unanimous ruling to remove Ariana Sampaio Souza from her position as a civil police delegate. The court overturned a previous decision that had allowed Souza to hold the post despite her low ranking in a 2017 civil police competition, concluding she did not meet the necessary requirements to advance in the selection process. ## Timeline ### 2026-10-23: Maranhão Court removes police delegate appointed despite low ranking The Maranhão Court of Justice has removed Ariana Sampaio Souza from her role as a police delegate after she was appointed via a court order despite ranking 2,018th in a 2017 civil service exam. 6 sources. https://clstr.news/cluster/maranho-court-removes-police-delegate-appointed-despite-low-ranking ### 2026-10-14: Maranhão police suspend delegate in corruption investigation Maranhão police launched Operação Quíron, suspending Regional Delegate Brito Júnior for 90 days amid investigations into corruption, fraud, and criminal association in Grajaú and Barra do Corda. 6 sources. https://clstr.news/cluster/maranho-police-suspend-delegate-in-corruption-investigation --- Cite as: Maranhão law enforcement investigations and judicial rulings.
