“Convinced that the man was up-to no good, the officer on patrol raised his colleagues who responded immediately and arrested the suspect,” he said.
Kinoti said Sh156, 421 (1,396 U.S dollars) were recovered from the suspect.
He was later handed to anti terror detectives, to establish his motives. He was found with a passport to suggest he is a U.S. citizen.
Lang’ata police boss Benjamin Mwanzi said they will seek to know his motives.
The country is on alert over different threats including terrorism.
Inspector General of Police Hillary Mutyambai directed that all police officers on leave should report back to work.
Regional police bosses have been instructed to ensure the order is implemented.
The country has about 120,000 officers drawn from regular police, APs, GSU and DCI.
At any given time, about 20,000 police officers are on leave, some including sick leave.
This come after an earlier order by president Uhuru Kenyatta for security agencies to be vigilant over instability in the region.
The president gave the instructions after Friday’s National Security Council meeting in Nairobi.
Uhuru gave the directive even as police officers put Sh50m bounty on five terror suspects.
The police put the bounty on missing terror convict Elgiva Bwire, Salim Rashid Mohammed, Mohammad Abubakar, Barigi Abdikadir Haila and Trevor Ndwiga.
