Inspector General of Police Joseph Boinnet asked the former officer to present himself to the nearest police station.
Boinnet said in a Citizen TV interview on Sunday that officers had been deployed to trail the suspected militant before he launches an attack.
"Those who veer off from the force know the consequences.
We are working better and smarter through a multi-agency operation to find such criminals," he said.
Police recovered three AK47 rifles and 178 bullets, during an operation targeting Ng'ethe,
at a river bank in Ruiru.
The operation followed that the man had been radicalised by the terror group that has carried out several attacks in parts of Kenya.
Ng'ethe deserted his job as an officer of the elite squad in 2014. He was a highly trained hostage and rescue cop.
Police said the suspect had been spotted at Riyadh Mosque, which is alleged to be the place youths have been radicalised, further cementing suspicion against him.
