New Delhi, Aug 28 - A bomb scare in a Delhi Metro train Friday night had the security forces on their toes after commuters noticed an unclaimed bag, which was later found to contain a lunch box and a mobile phone charger.

At around 8.55 p.m., passengers raised an alarm about a bag lying in a train heading towards Rithala on Line 1. The train driver called the security personnel and all the passengers were evacuated at Kohat Enclave, a few stations before the destination, an official said.

The empty train was moved to Rithala siding, where personnel of the bomb disposal squad examined the unclaimed bag and found in it a lunch box and a mobile phone charger, apparently forgotten by a passenger, the official said.
