Jarnail Singh Bhindranwale

Context: On 13 April 1978, a group of Amritdhari Sikhs of Akhand Kirtani Jatha went to protest against Nirankaris. The resulting violence led to the death of thirteen Sikhs. The death of the Sikhs shocked the Sikh community. The Nirankari leader, Gurbachan Singh was afforded a police escort to the safety of his home in Delhi by the Punjab police. When a criminal case was filed against him, the Baba had his case transferred to neighbouring Haryana state, where he was acquitted the following year. The Punjab government Chief Minister Prakash Singh Badal decided not to appeal the decision. Among Sikhs there was a great frustration at this perceived sacrilege and the legal immunity of the perpetrators. This gave rise to new organizational expressions of Sikh aspirations outside the Akali party. It also created a sentiment amongst some that if the government and judiciary would not prosecute perceived enemies of Sikhism, taking extrajudical measures could be justified. 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, which was banned by the government. When the Nirankari Baba was himself shot to death on 24 April 1980, the Baba's followers named Bhindranwale as a suspect, even though he was nowhere near the scene of the incident. Several of his associates and relatives were arrested. The FIR named nearly twenty people involved in the murder, most of whom 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. Lala Jagat Narain, the editor of a widely circulated paper in which he had campaigned against Punjabi being adopted as a medium of instruction in Hindu schools, urged Hindus of Punjab to reply to government census that Hindi and not Punjabi was their mother tongue and decried the Anandpur Sahib Resolution. He had also been present at the clash between the Nirankaris and the Akhand Kirtani Jatha. Jarnail Singh had often spoken against him, so his involvement was suspected when the well-known editor was found murdered on 9 September 1981. Two days after the assassination, police issued warrants for the arrest of Bhindranwale. A police search in Chando Kalan, a Haryana village, failed to produce an arrest. Upon seeing this, Bhidranwale publicly announced that he would surrender on 20 September. On 20 September 1981, Bhindranwale surrendered to the police at a function held in a Gurudwara Gurdarshan Parkash. Over the next twenty-five days while Bhindranwale was held in custody, sporadic fights erupted in areas where Bhindranwale's accomplices had gathered. Bhindranwale was released on bail on 15 October as India's Home Minister, Giani Zail Singh announced in the Parliament that there was no evidence against Bhindrawale. He left the Ferozepur jail a hero. CANNOTANSWER
