The National Investigation Agency (NIA) questioned two more persons from the city, believed to be 'close friends' of the duo who have been interrogated two days ago in connection with an Islamic State (IS) module busted in Kannur district last year.
A team of officials, led by a DSP from Kerala arrived here and took the youths to a police station for "questioning" about the movement of their friends from Karumbukadai and Ukkadam in the city.
According to police sources, one youth is running a shop that sells second-hand books and the other a shoe outlet in the city. They would either be released after questioning or taken to Kochi, they said.
