Funds managed by BlackRock, the global investment behemoth, emerged as the largest subscribers of the $750-million private bond issuance by the Adani Group.
BlackRock invested over $250 million, accounting for roughly one-third of the total issue.
Adani Group officials are under scrutiny following a US Department of Justice indictment in a bribery case.
BlackRock's move marks its first private placement in India's infrastructure sector.
