The Enforcement Directorate (ED) grilled Maharashtra Navnirman Sena chief Raj Thackeray for over eight hours in a decade-old money-laundering case involving realty deals and IL&FS, here on Thursday. Thackeray, who stepped inside the ED offices at Ballard Pier in south Mumbai around 11.15 a.m., finally stepped out at 8.15 p.m., even as his wife Sharmila, daughter Urvashi, and son Amit waited outside to receive him.
