The Enforcement Directorate (ED) has apprehended Amit Katyal, a purported associate of RJD chief Lalu Prasad and his son Tejashwi Yadav, in connection with a money laundering investigation related to the alleged land-for-jobs scam case. Katyal, who had been avoiding the agency's summons for about two months, was detained on Friday and subsequently arrested after questioning. His appearance is expected before a local court, where the ED will seek custody for further interrogation.
