The CBI has arrested Aman Singh, a key conspirator, in Dhanbad for irregularities in the NEET UG exam. Earlier, Dr. Ehsaan Ul Haq and Imtiaz Alam from Oasis School, Hazaribagh, and two others in Patna, were detained for their roles. The scam involves paper leaks, impersonation, and cheating. The National Testing Agency (NTA) faces backlash, leading to protests and demands for disbandment. The Supreme Court will hear related pleas on July 8. Following the allegations, the NTA cancelled grace marks for 1,563 candidates, offering a re-test, which 813 students took.
