Sandeep Wadhwa, arrested for his alleged role in a corruption case linked to supply of various logistical equipment for the Commonwealth Games, was on Tuesday remanded in CBI custody for four days by a Delhi court. Wadhwa, the MD of Comfort Net, which is a part of the Switzerland-based Nussli India consortium, was arrested on Monday by the CBI in connection with the 600 crore rupees overlays scam.Prior to Wadhwa arrest, the CBI had claimed that it had got some evidence against Nussli India which was given contract of nearly 140 crore rupees for supplying tents, portable cabins, containers and other items for six venues. According to the CBI, Nussli India had signed a memorandum of understanding with a Canadian firm's Indian unit for supply of steel-based modular fittings for Commonwealth Games venues. The CBI had earlier accused former CWG Organising entering into a criminal conspiracy with Binu Nanu, Director GL Events, in awarding contracts for overlays for different Games venues at exorbitant rates.
