Delhi/IBNS, Nov. 12 -- The Delhi Police have issued a city-wide alert to trace a red Ford EcoSport SUV, suspected to be linked to the Red Fort blast that killed nine people earlier this week.

The alert has been circulated to all police stations, border checkpoints, and posts across the National Capital Region (NCR), as investigators tighten the net around a widening terror network.

According to highly placed sources, the alert was triggered after investigators uncovered evidence suggesting that other suspects linked to the Hyundai i20 used in Monday's explosion were also in possession of another red Ford EcoSport believed to have been used for reconnaissance and logistical movements ahead of the attack.
