[3] Labh Singh was reported to be involved in the killing by some Indian news media but the CBI investigation contradicted the claim.

On 23 April 1983, while serving as the DIG of Police Jalandhar range, Atwal visited the Golden Temple in Amritsar to pray.

[11] 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.

Rather than go to the scene of crime, where Atwal's body lay unclaimed, both Grewal and Chahal left for Chandigarh in haste, where they met Governor Anant Sharma and then at night, Chief Minister Darbara Singh.

It established a fear of unknown gunmen and elevated crime among the locals as the CBI investigation found no evidence of Jarnail Singh Bhindranwale's involvement in the same.

As the law and order situation in Punjab continued to deteriorate Indira Gandhi made the decision of sending in the Indian Army to flush out the militants out of the Golden Temple in Operation Bluestar.
