On 13 August 1980 , a domesticated pig from the Dalit colony strayed into the Idgah during the Id prayer . Around 50,000 Muslims were attending Eid Miladun Nabi prayers at the location . The Muslims , who considered the pigs as haraam , believed that the pig had been deliberately released by the Hindu Dalits . They asked an on-duty policeman to chase the pig away , but he refused to do so , leading to a heated argument . The violence broke out when some Muslims pelted stones at the policemen . The Senior Superintendent of Police ( SSP ) collapsed when a stone hit his forehead , and the Additional District Magistrate ( ADM ) DP Singh was dragged away by some people ; he was found dead later . The policemen then started firing indiscriminately into the crowd . The police force was reinforced by the Provincial Armed Constabulary ( PAC ) troops that arrived in trucks along with the District Magistrate . Several Muslims were killed in the firing ; about 50 more lost their lives in a stampede that followed the firing . The Muslim leader Syed Shahabuddin later compared the firing to the Jallianwala Bagh massacre
