Officials said the incident happened at about 10:30 AM at the Uttam Nagar (West) station when CISF security personnel noticed an unattended bag at the X-ray baggage scanner at the station.
After conducting anti-sabotage checks, a senior official said the securitymen recovered from the bag a cash amount of Rs 7,62,622, a car key and two debit cards from the bag and it was kept in safe custody.
The CISF and Metro authorities got a phone number from the bag and a person identified as R Maini later came to claim the bag saying he had forgotten it.
