The National Investigation Agency (NIA) has arrested two more persons in Hyderabad as part of its probe into a suspected Islamic State (IS) terror module busted in the city last month.

Mohammad Ataullah Rehman and Naimathullah Hussaini have been arrested for their key roles in the ISIS conspiracy.

The two "were arrested on Monday after we found their role in terror acts. Both the arrested persons will be produced before the NIA special court today (Tuesday) and NIA will seek their custody for further probe," an NIA official told IANS on condition of anonymity on Tuesday.

Rehman, who is a resident of Hyderabad, was involved in radicalising the group members and also for administrating Bayah (oath of allegiance) to the Khalifa (Abu Bakr Al Baghdadi).

Forty-two-year-old Naimathullah Hussaini was arrested for contributing money to the terrorist fund collected by members of the group. He was appointed as the Amir of the group and participated in key conspiracy meetings.

The NIA had on June 29 busted an IS module by detaining 11 youth during searches at 10 places in the old city of Hyderabad. Five of them were arrested.

The two men arresed on Tuesday were among those six who were detained by the anti-terror agency. 

The NIA said the youth were conspiring to commit terrorist acts in various parts of the country. According to the agency, they were planning to target public places including religious sites and sensitive government buildings.

Nampally Court have sent four ISIS suspects arrested on June 29 in Hyderabad to eight days of police custody.
