Police officer Hiram Kimathi was arrested at his home in Kambakia, Meru County, on August 1, 2025, in connection with the anti-police brutality group Fighting Brutality and Impunity (FBI). This follows the arrests of other alleged FBI leaders, including Jackson Kuria Kimani alias Cop Shakur and former Kenya Defence Forces (KDF) officer Patrick Osoi.

• Kimathi's lawyer, Dan Kiruai, stated they were not informed of the charges or his destination.
• Patrick Osoi, a former KDF and US Army veteran, was previously arraigned and faces charges including preparing to commit a felony and terrorism-related offenses.
• The DCI alleges the FBI group, comprised of Osoi, Cop Shakur, and Kimathi, sought to recruit officers to defy 'illegal orders.'
