Security has been tightened in the American call centres after reports of threats to MNCs. Apart from city policemen; a Quick Response Team has been deployed. Every checkpoint is manned by four security guards and two armed personnel.
The blokes working there should take this threat very seriously. After Bombay Stock Exchange (economic power), Parliament (seat of democratic power), IISc (premier scientific institution), Varanasi (one of the holiest shrines) the next could very well be a symbol of India's new economic power.
