The NIA had arrested five people on June 29 last year, and said that they were allegedly plotting bomb attacks and indiscriminate firing at crowded places including religious sites and sensitive government buildings in various parts of the country.
They were allegedly being guided by an online handler suspected to be based in Iraq/Syria.
The NIA later made several more arrests in the case.
In the latest chargesheet, the NIA has accused 28-year-old Mohammed Irfan alias Abu Jafar, a mechanic from Hyderabadâ€™s Mir Alam Mandi area, of Collecting and transporting explosive material, among other things.
"Investigation revealed that Irfan took an oral oath of allegiance in favour of Abu Bakr Al Baghdadi, the self-proclaimed Caliph of the ISISâ€¦The electronic gadgets seized from the accused established his radicalisation towards ISIS ideology. He was in possession of materials like `Mujahid Guide' and `How to conduct lone wolf attacks' and was very influenced by Jihadi ideologues," TOI quotes NIA sleuths as saying.
