A suspected drug trafficker was ejected Friday morning from a Nairobi-bound bus from Moyale in a police operation and 417 grams of cocaine was found on him.
The narcotics were hidden under the inner soles of his rubber shoes.
Police said the suspect had swallowed more of the drugs and has since been put on watch to eat them.
This may take hours, officials aware of the issue said adding the value is expected to increase.
Acting on intelligence information, anti-narcotics detectives augmented by the Operations Support Unit intercepted the bus at the Blue Post section of Thika.
A 24-year-old man identified as Charles Obaga Kavehere was arrested.
The suspect was taken to the Jomo Kenyatta International Airport (JKIA) for further screening where detectives established that, besides the 417 grams estimated at Sh1.8 million, he had swallowed more drugs than he intended to ingest at the destination.
He was detained and fed with glucose pending the egestion of the swallowed sachets and further legal procedures.
Police have intensified operations to address cases of drug trafficking, possession, and consumption.
This has seen dozens of suspects nabbed in the operations.
The cases are pending in several courts while some have been convicted in the campaign.
Police have promised more operations in the coming days in efforts to address the menace.
Cases of drug trafficking have been on the rise in the country even as most traffickers avoid the main used routes in their business.
Police say they now use roads as opposed to airports to carry out their business.
The most commonly trafficked narcotics from Tanzania and through Uganda is heroin.
Cocaine is also trafficked from the two countries, police say.
A new trend shows some of the drugs are originating in Ethiopia, which has prompted more operations on the routes used.
Kenya made the second biggest seizure in July 2016 and arrested two suspects who were linked to the 100 kilograms of cocaine valued at Sh598 million disguised as sugar.
