In the first incident, Canadian national V Garg and his associate K Garg (Indian) were intercepted by the Central Industrial Security Force (CISF) personnel yesterday as they were about to leave the Terminal-3 building of the Indira Gandhi International Airport (IGIA), the official said.
They were stopped and questioned as the exiting the terminal area is not usually permitted for passengers, he said.
The duo told the security personnel that they used a cancelled ticket to enter the terminal area to see off their relatives who were travelling to Thailand, the official said.
They were subsequently handed over to the police as their ticket was fake and charged with alleged trespass, he said.
In a similar incident yesterday, an Afghanistan national K Waziri was apprehended in a similar fashion.
Waziri, who illegally entered the terminal to see off his father, was handed over to the police, they said.
