The incident took place on March 31 when CISF and Delhi police personnel were alerted about a four-member family which had boarded an Air India flight from Rajkot for Delhi.
Officials said as soon as the flight took off from Rajkot, a relative of family arrived at the airport there and informed security personnel about the possible "suicidal intention" of the fliers.
They insisted that they had some problem in their family and will share it only with the Prime Minister or the Gujarat Chief Minister or Delhi Police chief and if not allowed to do so, they will commit suicide at Jantar Mantar in the national capital, officials said.
They were counselled and subsequently made to board a return flight to Rajkot which landed there at 9:30 PM, they said.
They said the person identified as G Pradip got a fake ticket to enter the terminal area as he wanted to see off his family going to Dubai.
CISF personnel detected his suspicious movement and when they checked with the concerned airline, it confirmed that Pradip's ticket was fake. He was handed over to Delhi Police.
The police later arrested him under IPC charges, they said.
