Rulda Singh was shot July 29 in Patiala and he succumbed to his injuries at Post Graduate Institute of Medical Education and Research (PGIMER) in Chandigarh last month.

BKI activist Tara was arrested by Chandigarh police for his involvement in the assassination of the then Punjab chief minister Beant Singh but later escaped from Burail jail.
