The financial probe agency in a statement said that the assets were held in the name of shell firms Evershine Hospitality Private Limited, Skyrise Infratech Private Limited, Empire Sales Private Limited, Impress Estates Private Limited and Millennium Propcon Private Limited controlled by Qureshi.
"The immovable properties are located at Delhi, Rajasthan, Dehradun and Goa. The attached properties include a farmhouse located in Chhatarpur area of Delhi and an old fort in Bikaner district of Rajasthan," the agency said.
During investigation it was revealed that Qureshi was in touch with senior officer(s) of the CBI.
"He would collect money from different individuals either directly or through his agents such as Sathish Babu Sana to influence the cases being investigated by the CBI," the financial probe agency said.
Babu was a witness for ED in 2017 but in July this year, the agency arrested him alleging that he was close to Qureshi and was working for him.
A special court in Delhi granted bail to Babu in August this year. He was also at the centre of a turf war between the CBI's former director Alok Verma and his deputy Rakesh Asthana last year.
The ED alleged that proceeds of crime used to be laundered through various means such as expenditure abroad by Qureshi, his wife and their family members. The money was also sent through hawala.
The ED also alleged that other way of laundering was investment in properties, a major part of which used to be paid in cash.
"Investigation till date revealed collection of such proof of the case to the tune of Rs 12.69 crore out of which Rs 3.34 crore was already attached vide provisional attachment order on September 13, 2017," it said.
The ED said that since remaining amount has either dissipated due to expenditure or cannot be trailed due to cash transactions, properties having equivalent value of Rs 9.35 crore have been attached.
The Ed has filed a case of money laundering against Qureshi of AMQ Group of Companies, his employee Aditya Sharma, Pradeep Koneru of Timex Group of companies, A. P. Singh, former Director of CBI and other unknown persons and public servants on the basis of the CBI FIR.
