By Siddhi Nayak, Sarita Chaganti Singh and Nikunj Ohri MUMBAI/NEW DELHI (Reuters) - Indian lenders, including State Bank of India, are reviewing their exposure to Adani Group and examining whether they need to tighten their due diligence when offering new loans to them,

Adani, 62, one of Asia’s richest men, was thrust into the spotlight last week when U.S. prosecutors in New York charged him and seven of his associates with securities fraud.

Gautam Adani, Sagar Adani, and senior executive Vneet Jaain have not been accused with violating the US Foreign Corrupt Practices Act (FCPA), according to a statement released by Adani Green Energy Ltd (AGEL).
