The authorities in Meerut, northern India, have been accused of negligence over a fire which engulfed a trade fair and left 31 people dead.
At least 131 people were injured, 16 critically, after the blaze swept through tents at a fairground 80km north of New Delhi.
The 100m long steel-framed tents were capable of holding up to 2,000 people and had two exits, with stalls on either side, making it extremely difficult for people to escape once the fire began.
The fire engulfed the wooden-floored tents covered with synthetic material within seconds.
Police used batons to drive back hundreds of distraught and angry residents who massed outside the cordoned-off fairgrounds after the incident. An official said an enquiry had been ordered.
Local officials have denied that more than 100 people died in the fire, despite claims by relatives of the victims.
Many of those killed were college girls modelling for a show while others were sales girls for international electrical consumer goods manufacturers.
