Four Tanzanians were Wednesday evening arrested at the Jomo Kenyatta International Airport, Nairobi while trying to fly out with drugs believed to be cocaine. The four who include one man had arrived at the airport and wanted to fly to Hong Kong when police stopped them for a search. Airport CID boss Joseph Ngisa said they were put under observation and three of them had by Thursday morning emitted several pellets that they had inserted into their private parts. “They had inserted these narcotics into their private parts. They are emitting them slowly and we expect them to be through by end of the day,” said Ngisa. Police say they are still under observation and will be charged in court when they finish emitting the drugs. They had come to Kenya through Namanga border and were to fly out to Hong Kong.
