A British soldier collapsed and died Tuesday morning as he prepared to board a military ship at the Port of Mombasa.
The officer is suspected to have been drugged during a night out at a Mombasa entertainment spot Monday evening.
His wallet containing money and personal effects is missing.
Several suspects, including two Tuk Tuk drivers who took him and a female companion around the town are being held by police for questioning.
His body was removed to the Pandya Memorial Mortuary.
