Lucknow: The Uttar Pradesh Lok Ayukta has decided to drop charges of corruption and irregularities against former Chief Secretary Neera Yadav and three other senior IAS officers after it found the complaints against them were unsubstantiated.

Justice S C Verma took the decision to drop the charges against the officials days before retiring as Lok Ayukta after investigating the complaints against them, informed sources said here today.

The complaints of corruption and other irregularities against the officials "were not found to be true and hence the inquiry has been dropped", they said.

They said present Lok Ayukta Justice N.K. Mehrotra had directed that the complainant and the officials concerned be formally informed of the decision.

Besides Ms. Yadav, those against whom the inquiry had been dropped are V.K. Gupta, Shashank Shekhar Singh and Sudhir Kumar.

The CBI had chargesheeted Ms. Yadav for her alleged involvement in the NOIDA (New Okhla Industrial Development Authority) land scam in 1994 when she was chairperson of the authority.

The Supreme Court later directed that she be removed from the post of U.P. Chief Secretary.
