The Vyapam scam involved rigging of entrance exams for government jobs and medical colleges in Madhya Pradesh by undeserving candidates between 2008-2013. Candidates paid bribes to officials through middlemen to get high exam marks or leak exam papers. The scam was uncovered in 2013 when 20 people were arrested for impersonating candidates. Over 40 people linked to the scam have died under mysterious circumstances since the investigation began. In 2015, the Supreme Court ordered a CBI probe into the scam and related deaths after political pressure grew. The full scale of the scam and involvement of politicians is still under investigation.
