Vyapam whistleblower Ashish Chaturvedi has written a letter to the Director-General of Police, Madhya Pradesh, saying he has been kept under “conditions of house arrest” since January 13, a day after he testified in the special Vyapam court in Gwalior in the ongoing investigation into the corruption case.

In an interaction with The Hindu he said: “At night, two police persons, who have been appointed in the name of providing me security, enter my house and lock it ensuring that I do not go out. So, from 10 p.m. to 10 a.m., I’m virtually under house arrest.
