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 two were intercepted near an airline desk and it was found that they were "impersonating" and carrying the Aadhaar cards of others, the officials said.
"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.
