The top five floors of the building that houses Chennai Silks caved in this morning because of the intense heat. Thick smoke was soaring into the sky. The fire began at 4 am yesterday in the seven-storey building, reportedly as the result of a short circuit.
Declaring the area unsafe, the police have cordoned off the busy T Nagar which has forced the shutdown of other shops and offices in the area for two days. Zero visibility was reported in the area.

The fire began Wednesday morning in the 7-storey building, reportedly due to a short circuit.
"We had to demolish a portion of the front exterior of the building so that water could be let deep inside," a fireman was quoted as saying by the Press Trust of India.
Officials said the showroom stocked plastic items and clothes. The building had false ceilings which caught fire quickly.
