"People appear to have died due to suffocation," District Magistrate Manish Kumar Verma told reporters at Patna Medical College and Hospital (PMCH).
Senior Superintendent of Police Manu Maharaj echoing him attributed the tragedy to 'asphyxiation'.
"CCTV footage shows movement of a huge mass of people and there is no clear picture of stampede visible in the footage ... The incident (the deaths) seems to have happened due to suffocation," he said.
He denied lathicharge by police, which eyewitnesses alleged triggered the stampede and at the same time did not rule out the role of rumours as part of a 'conspiracy' behind the tragedy.
Some people are being questioned in this respect and the police was in the process of registering an FIR in the incident.
"We are also checking how far the falling of an electric wire or a ditch in which the feet of some people were trapped caused panic among crowd are true," Maharaj said.
"Gates were not closed. All the four gates including the one for VIPs were open... This can be seen in CCTV footage which cannot lie," he asserted.
Asked about the poor light condition in Gandhi maidan, the DM said lighting arrangement was the responsibility of the Puja committee. He said some lights were functional while some others were not working.
