Detectives in Mombasa on Friday seized a consignment of cocaine estimated to be worth Sh100 million from a house in Utange estate.
The consignment, some that had been packaged ready for market, was seized by officers from the Transnational Organized Crimes and the Anti-Narcotics units following intelligence leads.
During the operation, a 29-year-old female suspect identified as Nuru Murshid Mahfud, who is believed to be a mule, was arrested.
The Directorate of Criminal Investigations (DCI) said the drug substance had been in 35 sachets and concealed in suitcases and it is not clear whether it was meant for local consumption or was on transit to a different destination.
The suspect is being held at a police station in the coastal city as the undercover agents hunt for her accomplices.
Experts at the Chemistry and Toxicology units based at the DCI National Forensic Laboratory will be conducting more tests on the highly addictive drug, the biggest recovery yet in as many months.
