Sources said the police was alerted about terror threats, especially from banned Kashmiri militant groups.
“In order to preempt a possible terror strike, intensive checking at all vulnerable points, including crowded market places, parking lots, malls, etc has been ordered. We have increased police visibility in all areas,” a senior police officer said.
“An elaborate ground-to-air security apparatus was put in place across the capital, especially near the Parliament complex, international airport, inter-state bus terminals, railway stations, Metro stations, India Gate, Connaught Place and Red Fort, to deal with any untoward activity,” the officer said.
