Shamim (40) fell from the third floor balcony of Maqbool Apartment on Exhibition Road on Sunday night, Superintendent of Police (City) Anwar Hussain said.
He was rushed to a nursing home where he died later on Sunday night.
Anwar Hussain said the incident was being investigated whether it was a case of suicide despite Shamim's in-laws claim that it was an accidental fall.
Shamim was staying with his in-laws in Patna for the past two weeks and his wife Rabia was away in Dhanbad when the incident happened.
