Anti-narcotic detectives on Monday arrested seven wanted drug barons and seized heroin worth millions in Mombasa.
Regional police boss Larry Kieng said they also impounded seven vehicles hidden in a home in the Nyali suburb.
A campaign car branded Joho, for Mombasa Governor Hassan Joho, was among those seized. It is not clear whether it belongs to him.
The suspects were also found with Sh4.5 million and $10,000 cash, believed to be proceeds from drug smuggling.
Three of them were identified as Abdullahi Ahmad Kheri (Tanzanian), Hope Brenda Mbaga and Musa Athumani Kihara.
When they were taken to court, the prosecution said the Tanzanian is a flight risk.
Police were given five days to complete their investigation.
