The move came after BJP MP Nishikant Dubey wrote to the CVC last month alleging serious fraud to cheat the Union government and cause a huge revenue loss of Rs 500 crore to the national exchequer by Jet Airways in collusion with senior Civil Aviation Ministry officials.
The letter (of Dubey's complaint) has been sent to Chief Vigilance Officer of Ministry of Civil Aviation to furnish factual report to the Commission, official sources said.
Etihad had on April 24 announced its decision to purchase 24 per cent stake in Jet for Rs 2,058 crore. On June 13, the Foreign Investment Promotion Board (FIPB) deferred a decision on the deal, saying it required more clarity on control and ownership structure of Jet Airways. Jet chairman Naresh Goyal owns a 51 per cent stake in the airline.
Besides FIPB, capital market regulator SEBI, fair trade watchdog Competition Commission of India and Department of Industrial Policy and Promotion have also raised certain queries.
Dubey, who is a Lok Sabha member from Jharkhand, had early this month also written to Prime Minister Manmohan Singh, with copies to CBI, CVC and Cabinet Secretary Ajit Seth, alleging "strategic conspiracy" by some elements to get the deal approved.
The Revenue Department is also looking into the proposed deal to identify the beneficial owners and check whether or not it is structured in a way to evade taxes, sources added.
