Four persons have been detained by the Mumbai Customs Air Intelligence Unit (AIU) at the Mumbai Airport for violating the Foreign Exchange Regulation Act (FERA) norms as they carried digital phone memory cards worth Rs 52 lakhs.

The four passengers were attempting to walk through the green channel at the Mumbai International Airport without declaring their goods. They arrived from Hong Kong.

The custom officials were alerted about the four passengers and later they were detained and the memory cards were recovered after a thorough search.

The four will be taken to the Mumbai sessions court today, where the police would be seeking their custody for further interrogation.

It has been suspected by the investigating agencies that they were working for some organization, which deals in smuggling and are attempting to find out the mastermind behind the racket.

FERA Act, 1973, is an act to consolidate and amend the law regulating certain payments, dealings in foreign exchange and securities, transactions indirectly affecting foreign exchange and the import and export of currency, for the conservation of the foreign exchange resources of the country and the proper utilization thereof in the interests of the economic development of the country.
