The agency has issued orders for the provisional seizure of the assets, 1,625 immovable properties and fixed deposits, under the provisions of the Prevention of Money Laundering Act (PMLA).
The ED had clubbed 48 FIRs of the state police in this case and booked a criminal complaint under PMLA few years back.
"During investigation, it was observed that during the period 2006-2013, they (Ms PRP Granites and Ms PRP Exports) acquired about 1,625 immovable properties of registered value of about Rs 103 crore from the said proceeds of crime.
During investigations, it said, the agency noticed that the two firms and their partners "have entered into a criminal conspiracy to illegally quarry multi-colour granite stones from the non-lease hold lands.

It added that the probe found "they (firms and partners) used various machinery and explosive materials without adhering to statutory obligations and safety precautions causing harm to human lives.
"They forged and fabricated documents for transporting illegally acquired granite blocks so as to cheat the statutory authorities and to camouflage illegally earned income," it said.
"Thus the proceeds of crime were integrated and projected as money acquired through legitimate business."
An attachment of assets action under PMLA is aimed to deprive the accussed from taking benefits of their suspected ill-gotten wealth and such an order issed by the agency can be appealed before the Adjudicating Authority of the said Act within 180 days.
