Pune-based stud-farm owner Hasan Ali Khan surrendered before the Enforcement Directorate in Mumbai on Thursday night. The move comes after the Supreme Court cancelled his bail in a money laundering case and remanded him to four days ED custody. While entering the premises of the ED in south Mumbai, Ali said, he respects the apex court's order. The apex court initially remanded Khan to the ED's custody for 72 hours but extended it to four days following a plea made by Solicitor General Gopal Subramaniam. Mr Khan is also facing a 70,000 crore rupees tax demand notice from the Income-Tax Department as well as the ED probe.
