The Enforcement Directorate (ED) raided 37 sites belonging to private contractors in Delhi-NCR on Wednesday over an alleged ₹2,000 crore scam in constructing 12,748 classrooms at exorbitant costs. This comes after Delhi government's Anti-Corruption Branch registered FIRs against AAP leader and ex-Delhi Deputy CM Manish Sisodia and ex-Delhi PWD Minister Satyendar Jain in connection with the case.
