The National Investigation Agency (NIA) on Friday arrested three Indians, who are suspected IS supporters and had arrived at Indira Gandhi International Airport from abroad, an official said.
The three individuals identified as Sheikh Azhar-Ul-Islam alias Abdul Sattar Sheikh, Mohammed Farhan alias Mohammed Rafiq Shaikh and Adnan Hussain alias Mohammad Hussain have been booked under charges of criminal conspiracy of the Indian Penal Code and provisions of the Unlawful Activities Prevention Act.
"The three suspected IS supporters landed at Delhi airport on Thursday. They were arrested after questioning. We will produce them at a designated NIA court here on Saturday," an NIA official said.

The official said that the suspects resided in a foreign country.
The officials of the anti-terror agency further said that Azhar hails from Jammu and Kashmir while Farhan and Adnan are the residents of Maharashtra and Karnataka respectively.
