One of the alleged conspirators of the 2007 Ajmer blast has been arrested by National Investigation Agency (NIA) and remanded in 15 days of custody.
The agency will question Bhavesh Patel about the conspiracy behind the bombing as well as the murder of RSS member Sunil Joshi, official sources said.
NIA sleuths arrested Patel from in New Delhi on Tuesday and produced him before a designated NIA court in Jaipur on Wednesday which sent him to 15 days custody, they said.
Patel is alleged to be one of the main persons involved in planting the explosives at the dargah in October 2007 that left three persons dead and 20 injured.
The sources said the questioning of Patel may also help the agency in unravelling the mystery behind the murder of Joshi, one of the main accused in the Ajmer dargah and Samjhauta blasts, at Dewas in Madhya Pradesh.
The NIA has arrested at least nine persons in connection with the murder of Joshi and explosions in Samjhauta train, Malegaon and Mecca Masjid blasts in Hyderabad.
Patel is alleged to have planted the bomb inside the shrine on the direction of Joshi, the sources said, adding the accused was involved in planning the terror act as well.
The arrest of the accused is expected to unravel the fate of other members of the terror module who have been absconding over a period of time.
Patel had also allegedly helped in procuring SIM cards and mobile phones used as timer device to carry out the blasts at Ajmer and Mecca Masjid in Hyderabad, the sources in the NIA said.
