Eight Kenyans are among 12 suspected drug barons arrested in Mombasa during a joint security operation on Thursday night.
The suspects, including three Italians and a Mauritian, are expected in court on Friday morning.
Among them is a wanted suspect identified as Stephen Bosire who is said to operate in Diani.
He allegedly supplies large amounts of narcotics from neighbouring countries, namely Seychelles and Tanzania.
On February 17, Bosire’s accomplice Musa Kibiringe was arrested after he presented himself to the DCI.
The arrest came days after Anti-narcotics detectives nabbed five most wanted drug barons in Mombasa amid a government operation to eliminate them.
Swaleh Yusuf Ahmed was apprehended alongside his wife Asmah Abdallah, and other accomplices: Rashid Athman, Athman Salim and Farida Omar.
Swaleh is said to be a close ally of Bosire.
Coast regional coordinator Nelson Marwa said the five were arrested at an apartment in Bamburi.
The crackdown was carried out by detectives who were behind the arrest and extradition of four suspected drug traffickers to the US.
Baktash (40) and Ibrahim Akasha (28) and foreigners Vijay Goswami (Indian) and Hussein Shabakash (Pakistani) were flown to New York on January 31.
They were arrested in Mombasa for conspiracy to smuggle heroin and methamphetamine into the United States.
