ABVP leaders Shashi Ranjan Akela and Vimal Tomar have been charged under Section 302 for the murder of Professor Sabharwal.
The two men, who surrendered on Wednesday, were earlier sent to jail for 15 days merely on charges of disturbing the peace.
However, they were produced in court again today and have been sent to police remand till September 2nd.
Video footage broadcast repeatedly on all TV news channels clearly showed them threatening two professors of Madhav College in Ujjain.
Although Professor Sabhwarlal's son Himanshu has said that the fact that the two student leaders will now be booked for murder is a step in the right direction, the police has thus far been accused of a cover-up.
In fact, the Jabalpur High Court also has admitted two writ petitions demanding a CBI inquiry.
Himanshu, on the other hand, is also disappointed that it's taken so long for any action to be taken, and plans to approach the Supreme Court.
NDTV: What do you have to say now that they have been booked?
Himanshu: It is a welcome progress. For six days the entire nation fought for it and it's so unfortunate that it took them so long. But where are the other six people named in the memorandum sent by the professors?
NDTV: Will you still go ahead with the petition?
Himanshu: Yes, there is no political will, so how do I trust them? Once it's out of the media glare they will again try to manipulate it.
NDTV: Do you think this will redeem some faith?
Himanshu: It's a democracy and when so many people fight for it they had to do something to save their skins. Where are the other seven people? Media played the footage for 24 hours, they had to do something.
NDTV: Do you think it's because of media pressure?
Himanshu: Of course, yesterday they booked them and made a big deal about it. We pointed out the sections. If it was someone illiterate, they would have gotten away with it.
