Delhi court has refused to cancel the non-bailable warrants (NBWs) against Shravan Gupta, the former managing director of realty major Emmar MGF, in connection with the AgustaWestland VVIP chopper money laundering case, saying he was not cooperating in the investigation. The court said Gupta's application seeking cancellation of the NBWs was without any merit and also noted that the warrant was issued against him on August 29 as he did not join the investigation despite receipt of summons and was trying to evade the probe on one ground or the other.
