The incident took place yesterday after the Central Industrial Security Force officials, who were on a high alert in the wake of the Republic Day security arrangements, found two people inside the terminal building of the Indira Gandhi International Airport (IGIA) behaving in a suspicious manner.
The duo had taken the Aadhaar cards of two people who did not show up at the airport and were supposed to travel in a group of 20 people travelling to Goa.
"The two men, Mohammed Mustaqueem and Adil, have been handed over to Delhi Police which has registered a case against them," a senior official said.
The police was probing if the two men were part of some human trafficking or travel racket, he said.
