Sleuths of the National Investigation Agency (NIA) on Thursday detained two youth in Chennai in connection with their alleged links with the ISIS.
Police sources here said that the NIA team from Kerala picked up Sadique and Sahul at a city hotel for questioning.
Though they let off Sadique, the sleuths, led by DSP Subash Chand, took Sahul with them for further interrogation.
NIA sources said that the sleuths came to Chennai after they received a tip off from Subani, who was arrested in Tirunelveli few days ago, for his alleged links with ISIS.
