Speaking during a press briefing, Gachagua said the alleged attack occurred on Sunday in Witima, Othaya constituency, while he was attending a political engagement.
He claimed the group, which he described as a special undercover unit operating outside the formal chain of command, attempted to intimidate and harm him under unclear circumstances.
According to Gachagua, the officers were not in uniform and did not identify themselves, raising serious concerns about the legality of their actions.
He accused the state of deploying security agencies to silence political dissent and intimidate opposition figures.
He further claimed to possess evidence, including vehicle registration details and eyewitness accounts, linking the alleged officers to the incident.
Gachagua demanded that the Inspector General of Police and the Director of Public Prosecutions immediately intervene and ensure the officers are arrested and charged.
The former deputy president warned that if no concrete action is taken by February 16, he will mobilise nationwide demonstrations to protest what he termed as state-sponsored political violence.
The allegations come amid rising political tensions, with opposition leaders increasingly accusing security agencies of harassment, surveillance, and abuse of power.
Gachagua’s claims add to growing scrutiny of the National Police Service, which has recently faced public criticism over alleged politicisation and selective enforcement of the law.
Police authorities have not issued a detailed response to the specific allegations, but earlier statements from the Interior Ministry indicated that investigations into the Othaya incident had been referred to oversight bodies, including the Independent Policing Oversight Authority (IPOA).
Nevertheless, the former deputy president insisted that the matter goes beyond personal safety and reflects a broader pattern of intimidation against political opponents.
