Meanwhile, four fire accidents were reported in the state during Diwali celebrations. Three of the incidents occurred in Hyderabad. While there were no casualties, the accidents led to a huge loss of property.

A fire accident occurred in a flat at an apartment building in Himayatnagar in the heart of the city. The fire was triggered in the flat on the fourth floor by a burning Diya (earthen lamp). The inmates had gone out after locking the flat.

The residents of the apartments ran out in panic. Fire service personnel battled the fire for an hour with the help of three fire engines to douse the flames. An official said the flat was completely gutted in the incident.

In another incident, a fire broke out in a warehouse of electrical appliances on RP Road in Secunderabad when a firecracker fell on it. Three fire engines rushed to the spot to control the fire. A major tragedy was averted as there was no one in the warehouse.
