The ED is investigating I-PAC for alleged money laundering tied to a coal smuggling syndicate, for which it conducted searches at I-PAC offices and the residence of its director, Pratik Jain.
The agency has alleged that West Bengal Chief Minister Mamata Banerjee and police officials obstructed the raids and removed key evidence from the sites.
Banerjee, TMC and I-PAC have said that the raids are politically motivated.
