A suspected recruit of the Islamic State group was detained at the Pune airport on Tuesday while he was trying to leave the country.
Officials identified him as Raoof Ahmed, a resident of Bhatkal in north Karnataka. He had allegedly planned to travel to Syria via Dubai.
Officials said the Union home ministry had issued a Look Out Circular against Ahmed.
Security agencies had been monitoring him after his name cropped up during internet chats with members of the West Asian terror group, which controls large swathes of Syria and Iraq.
At least 14 men have been arrested this year by the counter-terrorism National Investigation Agency (NIA) as part of its probe on indoctrination of youths by the banned group.
The Indian security establishment suggests that around 20-odd Indians are currently fighting for the banned outfit in Iraq and Syria.
In 2014, a youth from Kalyan in Maharashtra had returned home after spending about six-months with IS. He was arrested upon arrival in Mumbai.
