Martha Karua, leader of the People Liberation Party (PLP), has called on the Independent Policing Oversight Authority (IPOA) to probe a violent attack on opposition figures on July 27, 2025, during which Nyandarua Senator John Methu's vehicle was fired upon by police.

• The incident occurred in Murang'a, targeting senators and MPs allied with former Deputy President Rigathi Gachagua, whom Karua likened to an assassination attempt.
• Karua presented evidence, including bullet holes in vehicle windshields, to IPOA and demanded accountability for officers involved, specifically naming Inspector General Douglas Kanja.
• Senator John Methu described the attack as an "assassination attempt," noting his vehicles sustained extensive damage from police action.
