According to district administration officials, rumours that a live high tension wire had fallen to the ground led to the stampede.
Other local residents like Kamla Prasad and Munna Kumar, a shopkeeper of nearby, said that after people panicked due to rumours and tried to flee, hundreds of vehicles parked near the gate and roads created the hurdle and caused the stampede.
"It was duty of local administration and police not to allow parking of four and two wheelers at the Ramghulam square near Gandhi Maidan as it connect to Exhibition road which has been congested in view of ongoing construction of flyover. The entire stretch of Exhibition road is encroached due to construction work," they said.
Additional Director General of Police Gupteshwar Pandey said a probe into the cause of the stampede has begun.
Bihar Chief Minister Jitan Ram Manjhi has ordered a probe by the state home secretary Amir Subhani and Pandey.
Manjhi had visited the hospital where the injured are being treated late Friday and inquired about their condition.
