Sections imposed on attackers of Motihari professor "laughable": Letter to Nitish

In a letter to Bihar chief minister Nitish Kumar, the Jamia Teachers’ Solidarity Association (JTSA) has said that the "brutal assault" on Sanjay Kumar Yadav, assistant professor of sociology at the Central University, Motihari, on August 17 by a gang of around 20-25 goons, which dragged from his third floor flat into the street, preceded an atmosphere of intimidation and threats of violence against him.
According to JTSA, in his complaint to the police, Sanjay Kumar has clearly named the ring leaders of the mob. It also records the incessant harassment and threats issued by Sanjay Kumar Singh, Bureau Chief, Dainik Bhaskar. These threats pertained to his opposition to the vice chancellor against whom the university teachers had been agitating, as well as his Facebook posts, one of which invited the wrath of assailants.

Calling it Jungle Raj, JTSA wonders why the perpetrators and those who threatened him, which can be ascertained from a video, have not been arrested. "The sections under which the FIR has been filed are laughably light", it says, urging him to "see the video and decide whether the mob attacking Sanjay Kumar with rods was merely engaging in wrongful restraint (S. 341), and a simple case of causing hurt voluntarily (S. 323)."
Wondering what would qualify as an attempt to murder (non-bailable S. 307) in his opinion, JTSA says, "We are surprised at the sullen silence of the government on this murderous assault. We can only conclude that your conscience has made peace with the lynch mob."
