Security personnel have restored two bags containing large sums of money to different commuters who had either forgotten or lost them while travelling in Delhi Metro.

The first incident took place on January 15 when an unattended bag was detected at Chawri Bazar Metro station by a Central Industrial Security Force (CISF) official who found Rs one lakh in cash and a laptop inside it.

After some time, officials said, a man identified as Sanjeev Gupta came back to the station looking for his bag which he had forgotten.

"The commuter was asked to provide bonafide information about the bag and upon satisfaction, the station controller handed over it over to Gupta," they said.

In a similar incident on the same day at the Saket Metro station, a commuter complained to on-duty Central Industrial Security Force authorities that his bag containing Rs 1.70 lakh has got exchanged after scanning at the x-ray counter.

Officials immediately checked the CCTV footage and found a 15-year-old boy picking the bag and going towards Hauz Khas station.

"The bags looked similar. The boy was intercepted by CISF personnel at Hauz Khas station and was asked to return to Saket station accompanied by force personnel. He admitted that he picked up the bag inadvertently. The mixed up bags were restored to the two passengers," they said.

The CISF is tasked to secure the Delhi Metro network.
