Under probe now is what appears to be evidence of how one of the Delhi Chief Minister and AAP national convenor Kejriwal's close relatives might have submitted forged bills for carrying out a civic project commissioned by the PWD department headed by Satyendar Jain.

Kejriwal's late brother-in-law Surender Kumar Bansal owned the Renu Construction company which was awarded a drainage project in Bakoli village along NH-44 in north-west Delhi in 2015, papers show. Renu Construction, according to official records, won the tender for quoting the lowest bid. But now, documents reveal what appear to be fraudulent means the chief minister's relative might have adopted to fleece the state exchequer.

On paper, Bansal is seen procuring construction material for the drainage system from a company called Mahadev Impex. But when India Today TV's teams visited its registered address at Sonepat's B-22 Industrial Area, the firm was nowhere to be found. Nevertheless, bills as high as around Rs 2 crore, issued by the non-existent Mahadev Impex, had been subsequently cleared by Delhi's public works department, pending completion of the project, show official documents obtained by non-profit Road Anti-Corruption Organisation (RACO) in response to its RTI petition.

According to petitioner Viplava Awasthi, the chief minister is suspected of having violated laid-down procedures to favour Bansal. "We demand a thorough probe into the PWD's working. The chief minister doesn't appear to be above board. He must also be subject to investigation into the forgery case involving his relative," said Awasthi.
