Security was today increased in the city following Bangladesh's worst terror attack by suspected ISIS terrorists at a cafe popular with expats.
"Police in the city have been sensitised following the terrorist attack in Dhaka," a senior Kolkata Police officer told news agency PTI.
He, however, said no alert has been sounded in the city.
"Our force is always alert and there is no system to issue high alert. We have sensitised the policemen and they are extra cautious now."
Security checks at various entry/exit points of the city were increased and every vehicle is being examined.
"This is being done not because of the terror attack in Bangladesh but as always, we are keeping a close watch on everything in and around the city to avoid any untoward incident," he said.
Twenty foreigners, including an Indian teenaged girl, were hacked to death by suspected ISIS terrorists inside a popular cafe in the diplomatic zone in Dhaka in the worst terror attack in Bangladesh before commandos launched an assault today killing six attackers and capturing one alive.
