The Enforcement Directorate on Wednesday carried out searches at the Pune residence of Sunil Shinde, the chartered account of businessman Hasan Ali Khan, who is facing charges of money laundering and tax evasion.
Searches are being conducted at Shinde's residence since early Wednesday morning, ED sources said. They declined to provide further details, saying the operation was still on.
Khan, the Pune-based stud-farm owner, has been arrested on charges of stashing away huge amount of black money in banks abroad.
The 53-year-old is also facing a Rs 70,000-crore tax demand notice from the income tax department.
