The Delhi Police Commissioner on Saturday held a meeting with other officials to review the security preparedness ahead of the festive season.
Sources said petrol pumps and petrol tankers could be targeted to spread terror.
Police personnel have been asked to step up anti-terrorist measures to deal with any untoward incident.
Sources told NB that in mid-September, two terrorists of Pakistan’s spy agency, ISI, were caught by the Delhi Police as they were planning to blast bridges, railway tracks and large gatherings in India. When caught by the special cell, about 1.5 kg of RDX was found from them.
“Such a large amount of RDX is enough to cause widespread destruction,” said officials with knowledge of the investigation.
Sources claimed that the role of the sleeper cell has also come to the fore in the interrogation.
The spread of influence from Afghanistan, where the Taliban is now firmly in control, could result in terror attacks in Delhi, sources said, adding that the militants have the support of the local population.
Police officials said that landlords, shopkeepers have to be vigilant.
Any illegal activity at cyber cafes, chemical shops, parking lots, junk dealers will be strictly monitored. Citizens have been urged to get in touch with the police if they find anything unusual.
Officials said there would be regular patrolling from 5 pm to midnight in busy, congested areas.
