Former Sports Cabinet Secretary Rashid Echesa was on Saturday reportedly rushed to hospital after his health condition allegedly deteriorated.
His legal team reportedly visited him at the hospital.
"My client's health deteriorated hence his admission to the hospital," his lawyer Danstan Omari said.
Police said they will guard him at the hospital ahead of his arraignment.
Echesa had asked the police to release him from custody to allow him to seek medical attention.
The former CS had been detained at Muthaiga police cells since Thursday night.
In a letter to the Inspector General of Police dated March 29, Echesa through his lawyer Danstan Omari wants to be granted cash bail to "continue with his journey towards full recovery."
"This letter is to request the Directorate of Criminal Investigations to authorize the Officer Commanding Muthaiga Police Station to take our client to hospital so that his doctor can review his medical condition as had been directed in our client's medical documents,” the letter says in part.
Lawyer Danstan Omari said his client had been detained to help with investigations into claims of abduction.
He, however, said, no report has been issued by police regarding the complainant.
