Four men were arrested on Wednesday in connection with the killing of a Banaras Hindu University (BHU) student in the campus premises on Tuesday evening in Uttar Pradesh’s Varanasi.

The slain student, identified as Gaurav Singh, was shot by four bike-borne assailants in front of the Lal Bahadur Shastri Hostel.

Singh, 23, was a suspended student of the prestigious institution. He was rushed to the Trauma Centre of Institute of Medical Sciences at BHU with bullet injuries where he succumbed on Wednesday.

Police immediately raided the campus hostels and adjoining areas in search of the assailants. Two of them nabbed have been identified as Rupesh and Abhishek Rai.

“We have arrested 4 people. It was a case of personal enmity,” ANI quoted Anil Kumar Singh, Circle Officer, Varanasi Cantt as saying.

According to reports the Crime Branch will be questioning the four arrested men.

According to students, Singh was talking to his friends when the bike-borne assailants gunned him down at around 7 pm. The incident caused panic in the campus, and students created havoc in the Trauma Centre.

Singh, whose father works at the BHU, was pursuing a Masters in Computer Administration from the college.

He was suspended for his role in the December 2017 bus-burning incident during protests at the BHU.
