The promoters of Hiranadini group, Niranjan and Surendra are in the dock after the Central Bureau of Investigation (CBI) registered a case against them on Tuesday, on the charges of evading Employees' Provident Fund (EPF) tax of Rs 168 crores.

The CBI claimed that they had credible information about the Employment Provident Fund documents tampered by Hiranandini group.

"The documents found in the raid show that the group has far lesser number of employees in its roll than they actually have," CBI sources said.

"By doing this fraud Hiranandani Group was misleading the government and simultaneously evading tax," the CBI alleged.

The CBI also carried out raids at the residences of four EPF officers to get some more proofs.

Hiranandani group is one of the biggest players in the real estate market.
