The incident happened on Panchanantala Road in Lake Police Station limits this afternoon when Balaji Shankar Sardar, a resident of Jamshedpur, exchanged one new Rs 2,000 currency note from a betel-leaf seller with two Rs 1,000 currency notes, a senior official of Kolkata Police said.
"Sardar was leaving the shop soon but the shopkeeper detected that the Rs 2,000 currency note was actually a colour photocopy of an original one. He started yelling and caught hold of Sardar with the help of a few locals there and informed the local police station," he said.
Sardar has been arrested and booked under IPC Section 420 on the complaint of shopkeeper.
