The Supreme Court on Thursday extended by four weeks the protection from arrest granted to Ambience Group promoter Raj Singh Gehlot in a money laundering case linked to an alleged bank loan fraud of Rs 800 crore. The Enforcement Directorate (ED), represented by Additional Solicitor General S V Raju, opposed the grant of relief before a bench headed by Justice B R Gavai saying the person who siphoned off hundreds of crores of rupees should not be granted bail allegedly on fake medical grounds.
