A large number of policemen were deployed on Monday at bus terminals, railway stations and shopping malls in Kolkata following the multiple blasts in Bangalore and Hyderabad.
Passengers at the long distance bus termini in Babughat and Esplanade in the heart of the city were being frisked, while large police pickets had been set up outside metro stations. At Howrah railway station, sniffer dogs were being used by the police to check for explosive devices.
"We have told bus drivers to be very alert and report to us the moment they find anything suspicious lying on the streets. Bus conductors have been told to keep a close watch on the passengers," said a police officer.
Security was also tightened in and around the vital Rabindra Setu, which connects the twin cities of Kolkata and Howrah. A large number of policemen was deployed on both sides of the bridge that is used by thousands everyday.
