On 12 July 1991, a bus carrying 25 Sikh pilgrims — including 13 men, nine women, and three children — was stopped by police at a checkpoint in Kachla Ghat, Budaun district, Uttar Pradesh. The pilgrims had begun their journey from Nanakmatta Sahib in Nainital district and were traveling toward Hazur Sahib Gurdwara in Nanded, Maharashtra, having visited several Sikh religious sites en route. Police, acting on a tip that militants were aboard, surrounded the vehicle with a large armed contingent and removed the male passengers, tying their hands and confiscating their belongings. Two elderly men were released, but eleven men were detained and taken away as the bus was diverted and escorted under police control, with passengers forbidden from moving or looking around.
On 14 July 1991, it emerged that ten of the eleven detained men had been killed the previous night in three separate "encounters" in the forested area near the Nepal border, an area now designated the Pilibhit Tiger Reserve. Police Superintendent R.D. Tripathi stated the men were terrorists linked to the Khalistan Liberation Force and Khalistan Commando Force. The status of the eleventh detainee, a 15-year-old boy named Talvinder Singh, has never been resolved. Independent investigations by media and political parties later concluded that only two of the ten men killed — Baljit Singh and Jaswant Singh "Fauji" — had documented links to militant organizations; the remaining victims, most from Gurdaspur, Punjab, and two from Amaria, Pilibhit, appeared to have no connection to militant activity. Witnesses, including the bus driver, later testified that police coerced blank statements and intimidated those who signed affidavits before the Supreme Court.
Public outcry led to Superintendent Tripathi's transfer on 23 July 1991. On 21 August 1991, the Supreme Court ordered interim compensation for the families of the ten men killed. The Central Bureau of Investigation subsequently charged 47 police officers in connection with the killings and their cover-up. In April 2016, a special court convicted and sentenced 47 officers to life imprisonment, and courts ordered further compensation to victims' families; by that time, several of the convicted officers had died. The convictions were appealed, and in 2022 the Allahabad High Court overturned the life sentences, instead convicting 43 officers and sentencing them to seven years in prison along with monetary fines scaled to rank.
This case remains one of the most prominent documented instances of extrajudicial killing associated with anti-militancy operations conducted under India's Terrorist and Disruptive Activities Act (TADA) during the Punjab insurgency era.
