Mr Kuria was grilled for three hours at the Directorate of Criminal Investigations (DCI) headquarters on Kiambu Road following complaints about offensive remarks he made in his constituency.
When he walked out, he accused the media of being biased on the issue. He insisted that he had no regrets over the remarks but he had apologised to those who misunderstood him.
?The truth will set me free because to me what I said was not inciting. I don?t know why the media is biased on this issue,? he said.
The first-time MP said the National Cohesion and Integration Commission (NCIC) was not fair.
?Francis ole Kaparo (NCIC chairman) should know he is holding a constitutional office and must be fair to all. Some MPs have been summoned over such remarks but ignored,? he said.
Kuria met DCI head of investigations Joseph Ngisa, who handed him to a junior officer for grilling and statement recording.
CID director Ndegwa Muhoro, who was in Naivasha for a meeting, said they would review the clip and attach it as evidence before forwarding the file to the Director of Public Prosecutions (DPP).
NCIC had petitioned the DPP and police to investigate Kuria.
DPP Keriako Tobiko moved to court under a certificate of urgency yesterday to seek the cancellation of bail given to Kuria in a previous case of incitement.
Tobiko also ordered police to hasten investigations and forward the file for action.
Kuria is alleged to have told panga-wielding youth in Kiambu to fight those criticising National Youth Service projects.
?These utterances in the opinion of the commission contravene Section 96 of the Penal Code, thereby requiring investigations from your end,? NCIC?S letter to Inspector General of Police Joseph Boinnet and Muhoro reads.
The MP was last year charged with incitement to violence and ethnic hatred but was released on a Sh2 million cash bail.
Mr Kaparo said the commission would step up pressure to tame the MP for repeatedly making hate remarks in public. He said he would lobby President Uhuru Kenyatta and all concerned State agencies for action to be taken against the MP.
Opposition leader Raila Odinga led other leaders in condemning Kuria, saying the remarks lend credence to his coalition?s concern that the Government has embarked on creating a militia.
