The National Investigation Agency (NIA) might take over the investigation in the case that has been registered against suspected IS activists arrested recently in Ratlam district.
Imran Khan Muhammad Sharif, leader of the four men was held in Ratlam on April 15, while his accomplices are in the jail.
The investigation conducted by Madhya Pradesh police so far revealed that the activists were allegedly hatching a conspiracy to target RSS and BJP leaders in the country.
Official sources claimed that the Union Home Ministry has asked the Madhya Pradesh Government to hand over the case to the NIA, which has been probing other terror cases related to alleged conspiracy to target political leadership of the country.
The investigation revealed that Imran Khan, Waseem, Rizwan and Anwar Qureshi were allegedly being motivated by Yousuf-Al Hindi, who is the face of ISIS for India and Bangladesh.
They said there was evidence that Yousuf, whose real name is believed to be Sultan Armar, had been killed in Afghanistan fighting the allied forces and his account was being handled by his brother Shafi Armar.
Sources claimed that cyber evidence, gathered over a period of time by Central security agencies and the anti-terrorist squad of Madhya Pradesh police, showed that the four were being persuaded by Yousuf for carrying out terror strikes. At the beginning, the cyber signature were traced to Afghanistan and lately to Syria.
During interrogation, sources claimed, the four had confessed to planning to carry out at least a couple of sensational attacks to mark the presence of IS in India. The questioning of the four as also cyber evidence collected by the security agencies indicate that Shafi has taken over the operations of ISIS in India and Bangladesh after the death of his brother Sultan.
Under instructions from Shafi, the four youths hailing from Ratlam district of Madhya Pradesh, had procured two pistols and were being guided for making improvised explosive devices (IEDs) from locally available explosives.
Imran Khan, who is alleged to be the group's mastermind, had travelled to Dubai five times during 2003-08 and once to Saudi Arabia last year.
