NEW DELHI: ED, which is looking to launch a probe into alleged money laundering by Bikram Singh Majithia, has found the charges against him to be prima facie based on conjectures and statements made by the accused.Sources said details shared so far with ED by Punjab’s vigilance bureau which recently arrested Majithia, show that the charges that he laundered Rs 540 crore of drug money are not backed with “corroborative evidence”. Majithia, a former state cabinet minister and brother-in-law of ex-deputy CM Sukhbir Singh Badal, has been in custody of Punjab police since his arrest on June 26.Majithia had first come under investigation of the anti-money laundering agency in the Bhola drug smuggling case in which two of his aides were arrested. However, the investigation was closed when he and his aides were exonerated.The vigilance bureau registered a fresh FIR against Majithia on June 25. Its case is based on a 2021 FIR by a Punjab police SIT, in which no chargesheet was filed, sources said.The SIT report, emanating from its FIR in 2021, was itself based on an ED report after the Bhola drug case investigation.
