Opposition leader Raila Odinga has rubbished the statement by police on Monday's invasion of public properties as inconsequential.
Raila said Kenyans are 'clever' and aware of all that happened.
"Hiyo ni upuzi na ujinga...si wao ndio walisema wajinga waliisha," Raila retorted.
He spoke Tuesday when he toured Northlands farm invaded by goons on Monday.
The land situated in Ruiru is owned by retired President Uhuru Kenyatta's family.
The absence of officers who he claimed had been allocated a portion of land inside the expansive farm to put up a police post even confirms the occurrence was not by 'accident'," he said.
"They want to say Kenya is short of stupid people, that Kenyans are stupid pretending not to be aware of what happened."
Raila alleged that the security agency was aware of the planned invasion into the farm including that of Spectre Limited.
In a statement, Inspector General Japhet Koome condemned the acts that led to the destruction of properties saying they have launched investigations.
He stated that those found culpable will be dealt with within the law.
"Our investigation into the destructions and injuries caused has begun, and those found culpable shall face the law. We are appealing to the public to adhere to the rule of law when exercising their Constitutional rights to picket, petition, or demonstrate," Koome said.
The IG said the attacks on police officers during the Azimio mass protests resulted in the injury of 23.
"Meanwhile, we commend our officers for discharging their duties with the utmost respect for the rule of law as demonstrated by their restrain during the unlawful protests."
