A CBI team on Monday visited the residence of former Bihar Chief Minister Rabri Devi in connection with "further probe" in the land for jobs scam case, officials said.

There is no search or raid taking place, they said. The CBI had already filed its charge sheet in the case and the special court has summoned the accused, including former Railways Minister Lalu Prasad and his family members and others on March 15, they said.

The agency has kept the further probe open into the alleged scam case, they said. The visit of the CBI team is in connection with further investigation in the case, they said.

It was alleged in the FIR that some persons, although residents of Patna in Bihar, were appointed as substitutes in Group-D posts during the period 2004-2009 in different zones of the railways located in Mumbai, Jabalpur, Kolkata, Jaipur and Hajipur and in lieu thereof, the individuals themselves or their family members transferred their land in the name of family members of Prasad and a company, AK Infosystems Private Limited, which was subsequently taken over by family members of Prasad.

It was further alleged that about 1,05,292 sq. ft. land situated in Patna was acquired by the family members of Prasad from those persons through five sale deeds and two gift deeds and in most of the sale deeds, payment to the sellers was mentioned to be paid in cash.

The value of the land as per existing circle rate was about Rs 4.39 crore.

The land which was directly purchased by the family members of Prasad from the sellers at a rate lower than the prevalent circle rate. The prevalent market value of the land was much higher than the circle rate.

It was alleged that due procedure and guidelines issued by the railway authority for the appointment of substitutes was not followed and later on, their services had also been regularised.
