630 grammes of heroin concealed in calabashes was on Tuesday seized at JKIA.
DCI director George Kinoti said the narcotics destined for Canada was intercepted following a tipoff from DHL security.
"Acting on information from DHL security on a suspicious consignment duped African calabash destined for Canada from Nairobi, the ANU officers moved with speed, confiscating the creamish powdery substance," Kinoti said in a statement via Twitter.
"After a verification procedure, the substance tested positive for heroin, which was then released to the detectives for safe custody as pursuit for the drug racket involved kicks in."
Last month, Morphine and cocaine concealed in kitenge buttons were also seized at JKIA.
A cache of the narcotics concealed in two shipments was destined for Australia from Kenya and had been declared as African traditional earrings.
Kinoti said an ordinary person would assume the 168 pairs of earrings to be just that.
"...but the deft police officers sensed there was more than met the eye. After deeper scrutiny, they discovered a yellow powdery substance cleverly concealed within the ornaments," Kinoti said.
The powder was subjected to presumptive tests soon afterwards and was positively identified as morphine.
According to Webmd, morphine belongs to a class of drugs known as opioid analgesics.
It works in the brain to change how your body feels and responds to pain.
