A Thai national has been apprehended at the airport here for allegedly carrying Rs 1.2 crore in old currency notes.
Officials said an input was shared by CISF sleuths deployed at Lucknow airport that some suspected cash is being transported by a person in his registered baggage, travelling to Patna.
Subsequently, the flier, identified as Thailand national S Parithan, was intercepted by CISF personnel at the airport here when he landed at about 6:30 PM, they said.
"The case has been transferred to Income Tax department. Total cash with Parithan was found to be Rs 1.2 crore in old currency notes. IT department authorities are checking the source of the cash," they said.
The Central Industrial Security Force (CISF), mandated to guard country's vital civil airports, has been keeping a special vigil to check on the movement of large cash in the wake of demonetisation.
