New Delhi, Sep 25 - Fake Indian currency nominally worth Rs.700,000 was detected at a Citi Bank branch in the national capital, police said Friday.

Citi Bank's Connaught Place branch manager G.S. Sawhney informed police after his staff detected the counterfeit notes a few days ago. Police registered a case under relevant sections of the Indian Penal Code (IPC).

According to police, the fake currency notes were deposited in the bank during the first five months of the year through cash deposit boxes in ATMs.

'We are trying to draw out a list of suspicious customers. Further investigations are on,' said a police officer.
