The police said that Deputy Superintendent of Police (DSP) Baljinder Singh Sandhu died from gunshot wounds from his service weapon. He had gone to a Punjabi University college in Jaitu, 255 km from here, to resolve the issue. Police officials said the incident was that of "accidental fire" by the DSP. Videos of the incident, shot by some people present on the spot, showed the DSP pointing his pistol at his own head and saying "I will shoot". Within seconds, a gunshot was heard and the officer fell to the ground. The DSP's gunman was also injured in the incident. Both were rushed to a government hospital in Faridkot town, around 225 km from here, where Sandhu was declared dead by the doctors.
