A violent disruption occurred during a thanksgiving service at Kariobangi North PCEA Church, attended by former Deputy President Rigathi Gachagua, leader of the Democracy for the Citizens Party (DCP). The service celebrated DCP's candidate David Wanyoike winning the November 27 by-election as Member of County Assembly (MCA) for the area. The party also clinched two other MCA seats in the mini polls: Douglas Masikonde in Narok Town ward and Aduda Okwiri in Kisa East ward, Kakamega County.

Police reports indicated that two groups of rowdy youths, reportedly armed, caused an altercation within the church sanctuary. Law enforcement mobilized reinforcements to calm the situation, with six people sustaining non-life-threatening injuries and receiving hospital care. Police spokesperson Muchiri Nyaga confirmed that the Nairobi Regional Police Commander and Directorate of Criminal Investigations (DCI) are investigating the “planned and premeditated” disturbance. Allegations of teargas use on worshippers were dismissed, as clergy had not reported any chemical deployment.

During the service, Gachagua directly accused President William Ruto and Nairobi Governor Johnson Sakaja of intimidating his political camp. He publicly addressed Sakaja: “Governor, my people voted for you. Why do you agree to be used by Ruto to send goons to bring mayhem to the people from my community?” Notable attendees included DCP Deputy Party Leader Cleophas Malala, Nyandarua Senator John Methu, and Embakasi North MP James Gakuya.

The attack drew sharp condemnation from former Interior CS Fred Matiang’i, speaking from St Peter's Cathedral in Kenol, calling the incident ironic in a country governed by the rule of law. He urged swift action against perpetrators, highlighting poor leadership as the root cause. Matiang’i signaled his intention to seek the presidency in 2027, promising to uphold law, order, and national cohesion, while warning against “increased money laundering and dirty politics.”

Murang’a Senator Joe Nyutu also condemned the “brutal attack,” pointing to outside forces funding political violence in the Mt Kenya region. Nyutu noted electoral malpractice in Mbeere North and urged former President Uhuru Kenyatta to pursue unity talks with Gachagua, suggesting that Governor George Natembeya and Wiper Leader Kalonzo Musyoka join the initiative to strengthen democratic space.

In a related incident, Sports Principal Secretary Elijah Mwangi faced heckling from Christians at a church event in Murang’a while outlining government development programs, including the Makeji Affordable Housing Programme, the national stadium in Murang’a, and Mukerenju Sports Academy. Bishop Karanu intervened, urging congregants to respect the sacredness of the church during public gatherings. Attendees included Jubilee Party Secretary General Jeremiah Kioni, MP Sabina Chege, and former MPs Kembi Gitura, Joshua Toro, Elias Mbau, Peter Kimari, and Njathi Mwenga.
