The clash triggered mass demonstrations, some violent, in
Punjab and
Delhi. The day following the clash, 250
Nihang Sikhs, armed with spears and guns, stormed a human unity Sant Nirankari conference, triggering further clashes, in which 28 people were killed and more than 140 were injured. Immediately following the clash, Sant Nirankari sites and holy places were beleaguered and threats of physical violence were meted out. The
Akal Takht later issued a
hukamnama expelling the Sant Nirankaris out of the Sikh community and proscribing any interlocution with them. They further directed Sikhs to use "all appropriate means" to prevent the Sant Nirankaris from "grow[ing] and flourish[ing] in society". A criminal case was filed against sixty two Sant Nirankaris, charged with the murder of 13 Sikhs, by the Akali-led government in Punjab. The investigation concluded that the attack on the Sikhs was planned by a number of accused, including Gurbachan Singh, all of whom were taken into custody except for Gurbachan Singh himself, who was arrested later in Delhi only after being permitted a personal audience with the
Prime Minister Morarji Desai. The Sant Nirankaris had firmly supported
Emergency rule, and developed close links with many Congress politicians and bureaucrats, creating a strong foothold in Delhi political circles; this gave rise to opposition from the Akalis and the Damdami Taksal during the same period. The case was heard in the neighbouring
Haryana state, and all the accused were acquitted on grounds of self-defence on 4 January 1980, two days before the
Lok Sabha poll. Though the case failed as authorities in Punjab were unable to ensure that the prosecution witness remained uncompromised by interested parties and police in
Karnal, the
Chief Minister of Punjab Prakash Singh Badal decided not to appeal the decision. The Sant Nirankaris received support from the media, who portrayed the incident as "inter-sect wars" and proof of rising Sikh orthodoxy, The chief proponents of this attitude were the
Babbar Khalsa founded by the widow, Bibi Amarjit Kaur of the
Akhand Kirtani Jatha, whose husband Fauja Singh had been at the head of the march in Amritsar; the Damdami Taksal led by Jarnail Singh Bhindranwale who had also been in Amritsar on the day of the outrage; the
Dal Khalsa, formed with the object of demanding a sovereign
Sikh state; and the
All India Sikh Students Federation. On 24 April 1980, the Sant Nirankari guru, Gurbachan Singh was assassinated. The Babbar Khalsa, who opposed Bhindranwale, claimed responsibility for the killing of Sant Nirankaris. Several of Bhindranwale's associates and relatives were arrested. The
FIR named nearly twenty people involved in the murder, claimed to have had ties to Bhindranwale. A member of the Akhand Kirtani Jatha, Ranjit Singh, surrendered and admitted to the assassination three years later, and was sentenced to serve thirteen years at the
Tihar Jail in Delhi. Ranjit Singh later became head of
Akal Takht. Ranjit Singh spent 12 years in jail as an under-trial from 1984 to 1996. Several other members of Sant Nirankari Mission were also killed later. The police crackdown in the state resulted in an average of 50 youths detained and 6 six killed per week, prompting a wider acceptance of Bhindranwale's claim that the government was out to destroy the Sikhs. The
People's Union for Civil Liberties, an Indian human rights group, accused the
Punjab Police of behaving like a "barbarian force". In response, Akali initiatives like
Raasta roko ("Block the Roads") and
Kamm Roko ("Stop Work" i.e. strike) drew massive popular support in Punjab, and seven other states supported Sikh demands for greater autonomy for Punjab and the decentralization of government power.
Later clashes Another clash occurred soon after in
Kanpur on September 26, 1978. A frenzied mob of 500 Sikhs armed with guns, swords and spears attacked a Sant Nirankari congregation. According to police reports, the Sikhs had set fire to the tents outside the venue and forcibly entered the meeting hall. In this clash more than a dozen Sikhs were killed in firing by police. In November 1978, another clash occurred in Kanpur after Akali Sikhs, armed with weapons, protested against a three-day Nirankari convention. The police were compelled to disperse the rioters with tear gas and rifle shots after they had attacked the police with swords. == Allegations of Congress involvement ==
