The Enforcement Directorate has unearthed the biggest Hawala racket in the country in connection with the 2G scam. According to sources, the agency found that the bribe money in the case had travelled through one of country's biggest hawala racket.

Sources further said that the role of a private bank was also under scanner.

Chennai-based JP Group helped former Union telecom minister A Raja, an accused in the 2G case, launder bribe money in the 2G scam, said sources.

The money reportedly travelled to a Dubai-based firm named Mycon General Trading Company. The money further travelled to Hong Kong and several other tax havens.

According to the sources, the probe was based on an input by the Research and Analysis Wing (RAW) in 2012-13.

The racket came to light when the Ahmedabad unit of the ED found that Surat-based diamond companies were running one of the biggest hawala frauds. The ED has, as of now, found evidence of Rs 10,000 crore being routed out of India.

Some arrests have also been made by the agency in connection with the case. While Afroz Fatta, Madan Lal Jain, Manish Shah and Rakesh Kothari have been arrested, warrants have also been issued against Mansook Lal Sanghvi and Dilraj Jain, who are absconding.
