New Delhi, July 26 - Shouting slogans and singing self-composed songs, holding banners and marching together, nearly 100 students, teachers and others came together here Sunday evening for a peaceful rally, demanding justice for slain Ujjain professor H.S. Sabharwal.

Organised by the slain professor's son, Himanshu, the protest at the India Gate evoked a lot of interest, especially from the student community.

'We came to know about the Sabharwal case from our professor in college and decided this was a cause we wanted to stand for. A teacher was killed by students in broad daylight and three years later nothing is done about it,' said Veer Singh, one of the several students attending the protest and holding a 'Justice for Professor Sabharwal' placard.

'It's just like the Jessica Lal and Priyadarshini Mattoo cases. Yesterday it was them, today it is Professor Sabharwal and tomorrow it could be me!' Singh, a Delhi University student, told IANS.

As they raised slogans like 'We want justice' and 'Professor Sabharwal's killers should be arrested', it caught the unwanted attention from policemen nearby who stressed that the protestors should stick to singing songs.

Sabharwal died soon after he was brutally beaten up by a group of students in Ujjain's Madhav College August 2006.

However, a court in Maharashtra, where the trial was transferred on Himanshu's plea, on July 13 acquitted six activists of the Akhil Bharatiya Vidyarthi Parishad (ABVP) - the students wing of the Bharatiya Janata Party (BJP) - of the charges of beating the professor to death. The court cited lack of evidence as the reason.

While Himanshu is still fighting for justice for his father, one of his close aides, Parminder Singh, was found murdered in the Delhi University campus Thursday night.

According to police, Singh, Himanshu and their friend Pooja were planning a candlelight vigil Sunday seeking justice.
