Apart from Hooda, the agency booked T.C. Gupta, the then Chief Administrator, HUDA and Director of the Urban Estate Town and Country Planning, and others, including 15 private builders, on charges of criminal conspiracy, cheating, pecuniary advantage and criminal misconduct,

An agency official said that the CBI registered the case on the November 1, 2017 orders of the Supreme Court to investigate the acquisition process of over 1,417 acres of land between 2009 and 2012 in Gurugram's Sector 58 to 63 and Sector 65 to 67.

Raids were being carried out since Friday morning in over 20 places, including the DLF office in Gurugram, and in Chandigarh, Rohtak, New Delhi and Mohali including Hooda's residence in Rohtak.

Hooda was expected to address a rally in Haryana's Jind city later Friday in support of Congress candidate Randeep Singh Surjewala.

The official said that the agency had earlier registered a preliminary enquiry to probe into the allegations. However, it remained tightlipped on more details about the case.

The CBI had recently received a go-ahead to file a chargesheet against Hooda in connection with the case.

The former Chief Minister faces allegations of using his influence to allot a plot for Associated Journal Limited (AJL), the parent company of the National Herald newspaper.
