Bhiwani (PTI): The Haryana police on Tuesday recovered the weapon used in the killing of the college student here even as protest against the incident spread to Sirsa.

Head Constable Karmbir, arrested in connection with the killing of 22-year old youth Kuldeep, a final year student, was remanded to two days of police custody.

Karmbir was brought by the police from Hansi in Hissar district and produced before a local court which sent him to police custody.

The head constable was charged with the killing of Kuldeep when he was returning home on the intervening night of Sunday and Monday.

However, none of the remaining seven police personnel who have been booked under section 120 B of the IPC (conspiracy) has been arrested so far.

A report from Sirsa said several students affiliated to All India Students Federation (AISF) and Indian National Students Organisation (INSO) staged a protest march demanding a CBI probe into the the killing of Kuldeep, action against the errant policemen and monetary compensation for his family.

The students also blocked the road in front of the bus stand and the national highway for about half an hour. Later, they also protested in front of the Tagore Bhawan of local Chaudhary Devilal University and locked its main gate.

At Kharak village, 18 km from Bhiwani, protesters blocked Bhiwani-Delhi road and when the police tried to remove the blockade they pelted stones on three buses.
