On November 19, 1981, 5 members of Babbar Khalsa and its chief Shaheed Talwinder Singh Canadian were staying in a house of Amarjit Singh Nihang in Daheru village in Ludhiana district. A police party headed by Police Inspector Pritam Singh Bajwa came searching for them. The Babbar Khalsa members opened fire as a result Inspector Pritam Singh Bajwa and Constable Surat Singh were killed. All 6 escaped. Those 6 persons were Wadhawa Singh (present chief of Babbar Khalsa), Talwinder Singh Canadian, Tarsem Singh Kalasinghian (currently in Netherlands), Amarjit Singh (Head Constable), Shaheed Sewa Singh (Head Constable) and Shaheed Gurnam Singh (Head Constable). Sewa Singh and Gurnam Singh, head constables, had later joined Bhindranwale and were martyred during Operation Blue Star. This is believed to be the first act which gained Babbar Khalsa and its chief Talwinder Singh Parmar notoriety. Kalasinghian and Talwinder Singh Canadian also later managed to escape from India, via Nepal border.
