Death
On 23 April 1983, while serving as the DIG of Police Jalandhar range, Atwal visited the Golden Temple to pray. While leaving the Darbar Sahib, he was shot and killed by a lone gunman. Two others were critically injured. The killing took place in broad daylight metres away from his bodyguards and official car. Immediately after the shootout, Atwal's bodyguard and car driver escaped in his car. A group of Punjab Armed Police jawans were stationed nearby but instead of nabbing the assassin, they also fled along with the crowd from the shooting spot. The militants from inside the temple came out to celebrate around Atwal's body and fired celebratory shots in the air. His corpse remained on the temple steps for several hours, and the Police force did not pick it up fearing further firings from the militants. Punjab CM Darbara Singh then telephoned Bhindranwale asking to allow the dead body to be picked up to which he agreed.

Labh Singh was involved in the killing.

Aftermath
The "Top Cop" Atwal's killing shocked the entire state of Punjab. It established a fear of Bhindranwale's gunmen among the locals. The Sikhs sympathetic to the Akali movement were also appalled by the incident as they viewed it as offensive towards Golden Temple. Akali leaders had an emergency meeting to discuss the aftermath of the murder. Akali Dal such as like Harchand Singh Longowal and Gurcharan Singh Tohra immediately denounced the murder in clear terms on record. Meanwhile, Jarnail Singh Bhindranwale described the killing as "the handiwork of the Government to malign Sikhs".

Chief Minister of Punjab Darbara Singh advised Prime Minister of India Indira Gandhi to send Police force inside the Golden temple. The law and order situation in Punjab continued to deteriorate further and leading to the PM taking the decision of sending in army to assist the local law enforcement and to flush out the militants out of the temple in Operation Bluestar.
