The ISIS module in Kerala which was busted by the National Investigation Agency (NIA) on Sunday was code-named Ansarul Khilafa. The arrest of the youths in Kanakamala was the result of NIA's meticulous planning that lasted several months.
The youths had created a separate group in the messenger app Telegram. Their team was led by a Kanuur native Mansid aka Samir Ali. The intelligence officials slyly became members of the group with fake addresses and kept a watch on the group's everyday activities and communication and closely followed each of the members.
In the meantime, the group discussed ramming a truck into the venue of Jamaat-e-Islami convention in Kochi. The intelligence helped prevent the attack. With that the group became inactive on Telegram and focused its efforts to track down the traitor among them. Finally, they decided to meet each other in person at Kanakamala in Kannur.
The NIA sleuths picked them up there.
