The government had issued a charge sheet against Khemka for “wrongly” cancelling the mutation.
Though Khemka could not be contacted today he had sometime back sent a detailed letter to Haryana chief secretary dismissing the charges against him.
The Haryana government had initiated a probe last year after it received a complaint that Khemka had allegedly changed the terms and conditions of the contract without approval.
Earlier in the day, official sources said here that the proposal for a CBI probe has been approved by Chief Minister Bhupinder Singh Hooda.
The state home department will now approach the Union Home Ministry for a CBI probe against the IAS officer.
The complainant had alleged corruption saying that Khemka as Managing Director had awarded the deal to a Gujarat based firm without following proper procedure.
