Delhi Police has beefed up security across city markets teeming with shoppers ahead of Diwali and other festivals.
The city has already been on a high alert since October 20 when a blast ripped through a wall of CRPF school in Rohini’s Prashant Vihar area.
The blast hurt no one but damaged hoardings of nearby shops and window panes of parked vehicles.
Prominent markets, including Chandni Chowk, Azadpur and Ghazipur, are especially on the radar of the police as many from outside Delhi visit them frequently.
