A social media influencer has been booked for allegedly duping a homeopath of Rs 4.5 crore by promising to get a medical college sanctioned in his name and "saving him from arrest" in a non-existent Central Bureau of Investigation (CBI) case, Nagpur Police said on Thursday.

The victim came in contact with the accused through a relative and spoke of his desire to start a homeopathy college, the Kotwali police station official said.
