Director of Criminal Investigations (DCI) Mohamed Amin on Friday blamed Thursday's attack on former deputy president Rigathi Gachagua on a lack of advance intelligence.
Mr Gachagua, who on Thursday accused the state of sponsoring violence against him with the intention of killing him, was attending the burial of Erastus Nduati, 23, at Bibirioni village in Kiambu County's Limuru constituency.

In a further drama, former Limuru MP Peter Mwathi and Bibirioni Ward MCA Christopher Ireri claimed they were abducted at the scene, bundled into Subaru cars and driven around before being dumped near Ruiru town.
"Thursday's incident in Limuru is being investigated and appropriate action will be taken against both the perpetrators and instigators," DCI boss Mr Amin told Nation.Africa .
Mr Amin advised all interested parties to desist from making allegations that are not officially made at police stations.
"If you claim to have been abducted, please report the matter to a police station so that we can assign investigators. If you saw the assailants or have any other vital information that can help us catch the criminals, let us know in confidence. We remain an impartial institution committed to the rule of law," said Mr Amin.
Mr Gachagua blamed the attack on loyalists of President William Ruto who, without naming them, he said were determined to make the Mt Kenya region a violent hub to hide what he described as an apparent loss of support for the government.
"The Head of State had on Tuesday spoken loudly against tribalism, intolerance and violence. His allies in Lamu and Kiambu have since contradicted him with hate speech and violence. The good leader in him is yet to speak out against it," Mr Gachagua told Nation.Africa .
Mr Gachagua was referring to a viral video clip on social media platforms showing Muslims for Human Rights (Muhuri) director Khelef Khalifa saying that Lamu County was not for the Agikuyu community and therefore they should not own land or seek leadership positions in it.
This came as a report from the Kiambu County Security Committee seen by Nation.Africa indicates that a message was sent at 10 am warning that six Nissan matatus had unloaded about 80 suspicious-looking men near Limuru Dairies.
Despite the warning, no team of police officers was sent to the area and when chaos broke out, Mr Gachagua - whose security detail has since been completely withdrawn - could only be saved by his privately procured bouncers.
Instead, Kiambu County police commander Michael Muchiri told Nation.Africa on Friday that the Gachagua attack was being handled by police headquarters.
"You should contact our police headquarters at Vigilance House. Our spokesperson (Dr Resila Onyango) will assist you," Muchiri said.
An update on the investigation at headquarters, which Nation.Africa has been privy to, sets out the roadmap for solving the Gachagua attack.
"Our ground teams have been instructed to review CCTV footage of the crime scene, identify high profile suspects who planned and financed the attack, review CCTV footage near the matatu terminus area where the attackers are suspected to have unloaded in several motor vehicles, issue summons to take statements and also interact with residents to gather post-attack intelligence," it reads.
So far, Kiambu Senator Karung'o Thang'wa has been summoned to the Central Region security committee to record a statement, a move he has criticised.
"I, along with others, had gone to the DCI headquarters to report the attack. But after the officers there refused to grant us an audience, the government summoned us to report to Nyeri County headquarters," he said.
Mr Thang'wa insisted that "the way the attack was packaged left no doubt in the minds of right-thinking members of society that the aim was to cause grievous harm to Mr Gachagua".
