Principal Secretary Home Amir Subhani told PTI that one more person died today, taking the toll to 33.
Twenty-nine others were injured of whom the condition of four patients was stated to be critical, Subhani said.
Of the 29 injured admitted to the Patna Medical College and Hospital (PMCH), 17 are women and 12 are men, he said.
Subhani, who along with Additional Director General of Police (Headquarters) Gupteshwar Pandey has been appointed to inquire into the stampede incident, said he would begin the probe with a visit to the spot at Gandhi Maidan at noon.
A large number of wailing people sat outside the PMCH the entire night looking for their near and dear ones who got separated in the melee.
Additional police force has been deployed at the incident site near Ramgulam Chowk.
The tragedy struck at around 7 PM yesterday at the South East corner of the ground near the Exhibition road when the people who were were returning after watching the "Ravana Vadh" (killing of demon king) event jostled with each other to move ahead, eyewitnesses and officials said.
Tens of thousands of people had gathered to watch the annual event at the historic Gandhi Maidan where several pockets were reportedly dimly lit when the stampede broke out.
Opposition BJP has criticised the Jitan Ram Manjhi government for the "lapses" that resulted in the tragedy.
