The government has asked both Patna and Gaya airports to put up posters inside the terminal buildings and make announcements to inform fliers about total prohibition in the state and requesting them to hand over liquor bottles, if any, carried by them to Central Industrial Security Force (CISF) personnel.

"These are necessary to ensure that there is no flow of liquor through the state airports. We held a meeting with the airport officials and impressed upon them to make passengers arriving here aware about the fact that Bihar is a dry state," registration, excise and prohibition principal secretary K.K. Pathak said.

Pathak added that the airport officials had been asked to tell the visitors that if they had by mistake carried liquor purchased outside Bihar or at duty-free shops at airports, then they should submit it to CISF before entering Patna or Gaya.

A senior official at Patna airport said the government request had been forwarded to the Airports Authority of India (AAI) headquarters in New Delhi for taking a final call. "We will take action once directions from the AAI headquarters come. Random checking of the luggage of passengers flying to the state has been started by CISF," the official added.
