The 45-year-old patient was said to have became unconscious and died shortly after being given painkillers for back pain and fever at a private clinic in the southern city of Hyderabad on Saturday.
Dr. Shiekh allegedly took the body on a motorcycle to an isolated location and doused it with petrol, but was stopped from setting the body on fire by alarmed locals.
The registered doctor, who had treated the victim on previous occasions, is in custody pending the outcome of the police investigation. He faces initial charges of murder and destroying evidence, a Police official said.
The body has also been sent for an autopsy to establish the cause of death.
Earlier this month at least 14 people in the western state of Maharashtra were left blind in one eye after bungled cataract surgeries.
Wow! Burn the patient-- so extreme.
