Chandigarh, July 8 -- Opposition parties in Punjab on Monday lashed out at the AAP government over the broad daylight murder of a businessman by some unknown bikers in Abohar. The parties termed the killing another reminder that the state's law and order has "totally collapsed" and demanded that chief minister Bhagwant Mann resign from the post. Several trade associations have called for a complete shutdown of markets in protest against the killing. Shiromani Akali Dal chief Sukhbir Singh Badal said the law and order in Punjab has "plummeted to its lowest point." "The shocking daylight murder of Sanjay Verma, owner of The New Wear Well Tailors in Abohar, underscores the prevailing jungle raaj. Businessmen and professionals including doctors, artists & athletes are facing grave threats from extortionists," he said. "I strongly condemn this brutal killing and offer heartfelt condolences to the Verma family. The perpetrators must be arrested immediately and brought to justice," Badal said in a post on X. Punjab BJP chief Sunil Jakhar said the killing was an "eerie reminder" of Punjab's law and order collapsing. "Deafening silence of the AAP Government after each such killing only emboldens the gangsters. CM Bhagwant Mann must tell Punjabis who is responsible for this blot on Punjab's name. Wake up, it's already too late," Jakhar said on X. Congress leader Partap Singh Bajwa demanded the resignation of Mann. "CM @BhagwantMann must resign! Punjab's law and order is in shambles. The govt must hold a serious discussion on public safety in the upcoming assembly session," Bajwa said. The leader of the opposition in the Punjab Assembly said, "This is not governance. This is complete lawlessness. @AAPPunjab has handed Punjab over to bullets and bloodshed." Punjab Congress chief Amarinder Singh Raja Warring alleged that Punjab was turning into a 'gangland'. Warring also referred to a doctor, Aniljit Kambhoj, being shot at in Moga. "... In both the incidents criminal gangs are suspected to be involved. What is the @PunjabPoliceInd doing? This calls for stringent action," Warring said on X....
