A terror suspect has been arrested while asking for information within Lang'ata shopping center.
Ali Abdullahi Hussein who is a Somali national was arrested at around 2am on Saturday.
Before his arrest, Hussein approached a police officer on patrol and cunningly sought information from him that the officer found suspicious.
The suspect sought to know on which day of the week a popular joint along Lang'ata road, hosts the largest number of patrons.
“The officer was puzzled by the questions from the suspect, who posed as an ordinary civilian seeking general information,” DCI director George Kinoti said.
Kinoti said when the officer hesitated to respond, the suspect offered a reward of Sh180,000 in exchange for the information that was not forthcoming.
“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.
