Khodabox, father of the child, filed the case against Dr Kazi Mohammad Ali Russel with Sadar Police Station on Monday.
Besides, a four-member body was formed to look into the matter.
The authorities concerned of Sadar Hospital formed the four-member committee, headed by assistant director of the hospital Dr Ansarul Haque.
The committee has been asked to submit its report within three working days.
According to the case statement, Ariful, son of Khodabox, a farmer, died on Monday, allegedly due to ‘wrong treatment’ at a hospital in Natore Sadar upazila.
Family sources said a toy whistle got stuck in Ariful’s throat while playing. Then they took him to a local hospital where the doctors referred him to Natore Sadar Hospital.
The on-duty doctor Kazi Mohammad Ali Russel took the boy to the emergency ward and tried to pull out the whistle by performing a surgery on his throat.
Then the boy started bleeding excessively and his condition started to worsen. And he died while being moved to Rajshahi Medical College and Hospital.
Dr Munzur Rahman, resident medical officer of Natore Sadar Hospital, said such a risky procedure should have been avoided.
