G A Sergeevich was intercepted by Central Industrial Security Force (CISF) personnel as he was about to leave the Terminal-3 building of the Indira Gandhi International (IGI) Airport on Wednesday, the official said.
The man, who holds a Russian passport, was stopped and questioned while exiting the terminal area where passengers are not usually allowed, he said.
The man had arrived at IGI from Ashgabat (Turkmenistan) early Wednesday, the official said.
He was subsequently handed over to police and charged with alleged trespass.
